Gold available572g (100 start + 444 kills + 28 bonus)

Leak damage if unopposed522 (10.4× the fortress's 50 HP)

Gold available assumes you kill everything. Against 31042.4 total HP, that is roughly 54.3 HP to remove per gold piece you will ever hold — a useful sanity check on whether this level wants more towers or more upgrades.
