With Furor Celtica, Celtic siege units are more hardy in combat, giving more time for support units to eliminate their attackers. Combined with their civilization bonus (faster firing rate) and team bonus (faster creation speed), it makes Celtic siege weapons one of the most fearsome in the game.
Team bonuses Edit
The Conquerors Edit
- Furor Celtica adds +50% HP to Siege Workshop units.
The Forgotten Edit
- HP boost reduced from +50% to +40%.
"The warriors of Celtic Britain gained a reputation as very emotional fighters, capable of wide swings in their morale. Furor Celtica, or Celtic Fury, was a state of highly charged aggressiveness that all enemy armies sought to escape. If the fury could be withstood, it might vanish suddenly and turn into panic. If the Celtic leaders could manage and direct the fury of their soldiers, it was a daunting force multiplier."—Age of Empires II manual description
