I want a Servent I can use for a little while for general content and nothing in particular (I would use one or the other until I get better DPS)
Just to dish out damage? Go for Medusa. Casters has a .9 attack modifier meaning they lack power while riders has 1 still Medea can spam her NP meaning lower damage, but more NPs. Medusa on the other hand has a harder time NP, but hits harder with her skill which increases attack damage.
Generally just go for Medusa and when fighting assassins go with Medea.
Medusa is great at farming vs Riders (Quick AOE NP who gives stargen to the party after fired, balanced QQAAB deck for either quick or Art chains with fellow Riders). And she can stun. Still prefer Ushi (even with she being ST) over her.
Medea first skill at level 4 (NP gaude +100%) and a NP bar refill based on overcharge allows her to spam her (very weak, yeah) ST NP. If you NP5 her, do her interlude NP streng up and slap a Heaven's Feel/MLB Formalcraft CE, her bad dmg is kinda fixed, as long as you use against assassins. She also remove buff in the NP, so her NP SPAM is quite useful for certain perky bosses who buff themselves all the time. And she has the classic AAAQB deck with Arts NP, que arts chain will follow easily. She's my main offensive caster, until I get either Xuangzang or Illya (Waver NP is good but does not hit, aside from curse).
