Gold available676g (100 start + 544 kills + 32 bonus)

Leak damage if unopposed666 (13.3× the fortress's 50 HP)

Gold available assumes you kill everything. Against 45276 total HP, that is roughly 67 HP to remove per gold piece you will ever hold — a useful sanity check on whether this level wants more towers or more upgrades.
