I've been wondering how to build Aloth in Deadfire. From what I understand, wizards are a class that DOES have strong benefits for staying single-class, namely some VERY powerful spells in the top tiers. On the other hand, multiclassing is pretty darn fun, and some companions can become quite powerful when they multiclass, as Pallegina and Tekehu demonstrate in the excellently written Tuono e Fulmine and Tāwhirimātea, The God of Storms builds (P.S. You're awesome Ascaloth!).
So...what about Aloth? Is it better to keep Aloth as a single-class wizard? Or would it be better to convert him to a Battlemage (multiclassing him with Fighter) or Spellblade (multiclassing him with Rogue), and if so which of the two multiclasses is better?
