Is Rebecca good?
Rebecca covers a wide area with her summons and hits hard on her ultimate thanks to a stacking passive that raises its multipliers. At Intron 7 she gets five summons that can blanket a whole area, making her especially good at farming in modes stacked with enemy waves.
She costs a lot of Sanity to keep her summons up though, needs real investment to click, and comes out just slightly behind Ada at I6 in pure damage if the summons aren't managed well.
Strengths
- Summons cover a wide area for both bosses and mobs
- Stacking passive boosts her ultimate's multipliers
- Free to unlock
- I7 gives her five summons at once for wave clearing
Weaknesses
- Heavy Sanity cost from casting multiple summons
- Needs high investment and good summon management
- Slightly behind Ada at I6 in raw damage
