Gold available293g (70 start + 203 kills + 20 bonus)

Leak damage if unopposed279 (5.6× the fortress's 50 HP)

Gold available assumes you kill everything. Against 13446 total HP, that is roughly 45.9 HP to remove per gold piece you will ever hold — a useful sanity check on whether this level wants more towers or more upgrades.
