Thief
The Thief starts with Dagger Attack and Stab, and unlocks 8 more as its skills level up, shown in the Skills table below.
Its rebirths reset only its own progress (see Rebirth). In its Rebirth upgrades below, tier 1’s give the bonus itself, and each later tier’s boosters make the matching upgrade from the tier before stronger.
