Yep, those chu chu water bombs came in handy to fight an Igneo Talus. I got side tracked, ended up in the Goron city instead of going back to the water temple. (Oof heat armor is expensive) It's kinda impossible to stick to a plan. Anyway he had the shrine quest thingie I needed and can't use bombs in the heat, so ice and water arrows. It still took 30 shots without missing once as I'm still on 4 hearts, insta death if he gets just one throw off. No quarter heart protection here.
Anyway I'm doing the shrines around Goron city while taking Yunobo along. He's very useful for breaking rocks and there are plenty tunnels to open around here.
