Idle Obelisk Miner Mega Bomb vs Infinity Bomb: When They Still Help

Player question: When are Mega Bomb and Infinity Bomb useful in Idle Obelisk Miner — are they pointless late-game, and do they still matter for early world pushes or no-upgrade challenges?

I like these games and play them myself. Complete guides are hard to find online, so while playing I collect community experience from Reddit, add a little of my own notes, and put this site together—hoping it helps. Thank you.

Quick answer

Community Knowledge Most players treat Mega Bomb and Infinity Bomb as minor tools once standard bomb damage and farming bombs catch up. Threads asking whether either bomb still matters usually get answers that they are essentially useless for routine progression, with Mega Bomb drawing extra complaints that it needs a rework[1][2][3] Even a new player who maxed Infinity damage reported not knowing what it gained them[4].

Community Knowledge They still show up in two narrow bands: no-upgrade or restricted-upgrade challenges that ask you to push deeper than your usual build allows, and early World 2 or early World 3 floor pushes before other bomb upgrades feel sufficient[1][2]. For how bomb caps and workshop upgrades fit into regular progression, see the Bomb Cap & Workshop Guide.

What players report about Mega Bomb

Community Knowledge Low priority once other bombs outscale it. In the dedicated Mega versus Infinity thread, top replies call both bombs essentially useless in the current game state, with only a few early edge cases[1]. Mega Bomb specifically is described as so weak that a long-running community suggestion thread exists about how to make it useful again[1], and other players shorthand it as effectively dead content[3]. All reports here are about the original, unmodded game as discussed on r/IdleObeliskMiner; none of the cited threads involve mods.

Community Knowledge Where it still gets mentioned: pairing Mega Bomb with Infinity Bomb for temporary ore marking or damage boosts while you are still early in a world, before workshop bomb damage and farming bombs take over[1][2].

Community Knowledge Late-game bomb choice shifts away from Mega. Once progression is further along, players report leaning on transmuter bombs, vein bombs, or experience bombs in niche cases rather than Mega or Infinity[1].

What players report about Infinity Bomb

Community Knowledge Rarely touched after mid progression. Players who max Infinity damage often say they did not need it for anything meaningful[2], call it worthless[2], or treat it as a relic of older design that only occasionally one-shot floors early on[2]. Some players who reach max Infinity damage describe doing it mainly for the satisfaction of completing it[2].

Community Knowledge Early worlds were the last common use window. Several players name early World 2 or early World 3 as the last time Infinity Bomb helped with floor pushes or star farming before other bomb damage made it obsolete[2][3]. If you are far enough along to max the bomb, you are often far enough that you no longer need it[2].

Community Knowledge Non-combat uses dominate late threads. Scaling threads turn into sharing personal multipliers, but replies mention keeping it around without firing it for damage, or using it mainly to poly its card[3]. Some players fire it only to satisfy challenge depth requirements, otherwise letting the multiplier climb for its own sake[1].

When they might still help

Community Knowledge No-upgrade and restricted-upgrade challenges. Multiple players name challenges that require pushing deep without buying upgrades or contracts as the main legitimate use for both bombs, because temporary ore marking or burst damage can reach floors your normal build cannot[1][2]. Infinity Bomb also gets fired to hit a specific challenge floor or level gate, not for everyday mining[1]. For broader challenge pacing, see the Challenges Guide.

Community Knowledge Early World 2 and early World 3 pushes. Several accounts describe using Infinity Bomb (sometimes alongside Mega Bomb marks) to push a few extra floors at the start of a new world before workshop bomb damage and standard bombs feel adequate[1][2][3]. That window closes once bomb damage scaling and efficient farming setups replace manual burst damage[2].

Recommendation Default elsewhere. If you are not in one of the situations above, community advice is to invest attention in bomb cap, workshop sequencing, and gem bombs rather than farming Mega or Infinity damage (see the Bomb Cap & Workshop Guide)[1][2].

    u/dontreadmycommemt: “Seems like they are completely useless? Is there ever a point where you use them?” — original post 1x81pv4

    u/iReddit_uReddit: “They are essentially useless” — comment ph91qus

    u/tesat: “Maybe some use cases early on. But other than that and in the current state of the game: useless.” — comment ph91r5l

    u/Fun-Cook-5309: “Useful for no upgrade challenges and pushing deeper when you're relatively early into a world.” — comment ph93735

    u/picabo123: “I used them for some of the challenges that wanted you to push deep without upgrades or contacts. Also for a day or two while pushing w3 floors before I had more bomb damage. After that I haven't touched them at all.” — comment ph91p8f

    u/RunCreeperRun: “There is a thread in the Discord that is 3k+ messages long for suggestions on how to make megabomb useful again. As far as infinity goes, the last you'll use it is if you are diving deep into w3 before you should be” — comment ph93qk9

    u/Moist_Mushroom5933: “Early W2 infinity bomb helps, like for 30 minutes or smth. After that you get mega bomb damage mark and it helps for few days in W2” — comment ph9j57r

    u/TheGracefulCrane: “I used infinity for damage when pushing higher levels early on for sure but late game ueah its just transmute or vein bomb or maybe exp in niche cases” — comment ph95g0i

    u/PlacePuzzleheaded333: “I fire infinity bombs when I have to get to a certain level for challenges, otherwise I just fire them to stack up the numbers ” — comment phapqtd

  2. What is the use of infinity bomb? (opens Reddit) — Whether maxed Infinity damage has a purpose, early World 2 and World 3 pushes, and comparisons with Mega Bomb.

    u/Fdeblasro: “I maxed the damage of infinity bomb. But I never had to use it for anything.” — original post 1wqoe8u

    u/RunCreeperRun: “Helpful for advancement through floors you don't have the damage for like completing challenges that require no upgrades to be bought. To be honest, I last found it useful sometime early W3.” — comment pc5jpbw

    u/ArithinJir: “It was pretty useful to push progression in early w2 and w3 with mega bomb. After that bomb damage scaling and efficient farming makes it obsolete.” — comment pc6pjhq

    u/HEY_GUESS_WHO: “I used it occasionally to one shot some floors early on, but in general it is useless now. It’s a relic of the games old design.” — comment pc5js2b

    u/Spirited_Draft_4489: “Early w3 was the last I used it. It has the highest damage out of all the bombs so it made farming stars early in w3 faster and progressing to higher floors easier” — comment pc5kgmi

    u/New-Replacement4798: “I've never used it and ive never needed it. Worthless bomb.” — comment pc8q4pp

    u/RunCreeperRun: “One shotting a rock is better than adding a damage multiplier. If anything you would use the bear drone to autofire basic bombs with the mega but that requires fast enough bomb recharge time and, depending on your current bomb damage relics, may still be less damage than your infinity bomb. There were some times where I mined things I really shouldn't have been using the mega for a multiplier combined with the infinity bomb, but that was more of a test of could it be done than actually being useful in practice.” — comment pc8u0ob

  3. Infinity bomb (opens Reddit) — Infinity damage scaling brag thread, late-game uselessness, and non-damage uses such as card polying.

    u/PFirefly: “I used it in late w1 and early w2 to push to higher levels for challenges and whatnot. ” — comment paomgtt

    u/mathbandit: “I just cycled it in my D20/Battery cycle. Not sure I've ever actually fired one for damage.” — comment parddek

    u/ExtrapolatedData: “I wasn’t aware anyone was actually using this bomb except to poly its card. I’m basically done with W3 and my infinity damage is at x44k” — comment pao4zzm

    u/Broad_Barnacle_9372: “Fr that bomb is useless” — comment pao8l57

  4. Infinity Bomb (opens Reddit) — New-player confusion about what maxing Infinity damage accomplishes.

    u/heraoff: “I don't know what this bomb is for. I just kept pressing "fire all" to get 99999x. It says "Congratulations." Okay, I understand. But I don't understand what I gained from it. ” — original post 1wjs1z5

    u/PuzzledDrama1160: “Yep. Most bombs are useless for about 80% of the game.” — comment pal53fz
