DeLorean DMC-12 (Unique Metropolis Tower)

My idea is this tower for incomming session,obtainable in session Black Market - Flux capacitator : 3% Chance to repeat current wave + 0,15 chance per tower level + 10% extra chance in boss or horseman wave - Doesnt working after reaching last wave Damage 21-45 Speed 2,8 Range 2 Cost 5250

Your idea is spreading. https://mazebert.com/forum/suggestions/time-warp--id1447/ https://mazebert.com/forum/ideas/flux-capacitor-mechanic-metro-tower--id1516/

My idea is send same wave after killing all enemies in current wave

Instead of repeating a wave to increase the number of creeps to kill, maybe the size of waves could have a chance to be increased. I think it would work as a Cthulhu-flavored tower/item that increases the size of the cultist waves. Implementing it as a unique tower would make it a commitment. If the tower also made cultist waves 10% stronger and increased the spawn rate, then it would be an interesting decision. Repeating a wave feels hard to balance and maybe too strong. Making a wave bigger can make it harder, but repeating the same wave that was already survived would be a clear benefit and a boring decision. Edit: I guess this is a bit like part of this suggestion: https://mazebert.com/forum/ideas/hexing-scepter-legendary-item--id1530/
