Fixed: the Sheriff's Hat achievement could not be unlocked
Fixed a bug where the Sheriff's Hat achievement could not be unlocked on the final boss fight (reported by afettuccine)
TipIf a final boss clear never handed you the Sheriff's Hat, that was the bug rather than the run. The unlock registers on that fight now, so the attempt is worth repeating.

Weapon range has been increased during the fight
Your weapons have more range during the final boss fight, so you can hit the boss from further away.

Orbs have slightly longer cooldown
The final boss's orbs have a slightly longer cooldown, so fewer of them fill the arena.
Orbs have slightly longer cooldown, so he doesn't spawn as many
TipA cooldown change lowers the spawn rate, not a total, so a boss fight you drag out still fills with orbs. Spend the wider gap between spawns pushing damage rather than waiting the fight out.
