Lucas with t5 weapon and armor, Gaspar, Luciano with t5 weapon. I have already finished whole region 5 with these heroesU can also try Maria (4****) for Luciano but she needs boost in elite training room for lethality+3 and dexterity +4. But for last story mission U need someone strong with t5 weaon and armor like Lucas. He has great skill which kills one target for one shot and U must save it for Torquemada. This is the only demanding task - last story mission.
Im sure that mission can also be done with Alvaro with tier 5 weapon and armor. I’m still waiting on the latter to drop for either Alvaro or Lucas (I have t5 weapons for both). In the meantime I’m crafting Gaspar a tier 5 weapon. That 1 gives him an extra slot for his field doctor ability so well worth the investment for missions like this.
