So which of the five available companions/origins would you like to play?
For me, Wyll and Gale are most interesting as a playable origin, and either one would complement my ideal party of Lae'zel, Shadowheart and Astarion.
Gale makes for an excellent evocation wizard, his own story and even his name highlight is affinity for elemental magic.
Wyll would make an excellent Pact of the Blade Warlock and his quest for redemption is intriguing.

Read the fine print.
