What does Relentless Assault do in Dragonfire?

Relentless Assault increases your damage against non-player (PvE) targets: AI tile defenders, bridges, Seats of Power, beasts.

• Effect: +1.5%/level (level 10 = +15%).

It's a global bonus (all troop types), so it applies to every PvE fight — and PvE is most of what you do for the campaign and for seats.

➡️ Excellent value: unlike the per-type Damage nodes (which only pay when you field that type), Relentless Assault helps all your armies the moment you hit a non-player. In one of Adel's early fights it was already worth +18%. High priority for a map/campaign-focused player.
