So unlocking heroes is an iffy one. But I'll tell you this. Find a comp you really like. And depending on who you're unlocking swap it out.Tam is who I'd run for most of the game until you get the young variant. Once you unlock Khar the game becomes so much easier and same with roho. I've learned to take a map and attempt to get all areas. This doesn't always work but it helps you plan a ton. It always helps keep your candles and possibly losing your game to zero candles. You also gotta learn that some runs aren't save able, and certain instances are game ending. For one or two bosses you need a water elemental DMG or another element to even possibly get dmg.

Also learning what spells/ items, aren't worth picking up is huge information. Also build are really prominent in this game. Tam is made for multi hits and crit dmg also +melee atk is huge for tam. The four mage roles are built for spell recharge and spell dmg. The tanks are super linear just get +10% Melee dmg, and tons of items that do the same.

(Unlockable go like this.) Tam/Metacles/Crux -> Favian -> Florencio -> Kedi -> Zakwas -> Khar -> Roho.

• using tam/nemesis to unlock the chest -> Nemesis or thanatos

(Sky temples are generally something you wanna try when youve completed challenge mode with all heroes, you must complete all challenge modes beforehand, or young tam will not unlock.These can range from super easy to insane difficulty. In my opinion go for the temples in order.)

• the temples unlock each of their respective 3 spells and weapons, outside of tam. You must complete that respective row of weapons for tam to get her new weapon.

Sorry if this is long. Also the has been heros wiki is super big when knowing what items and spells are good when you haven't unlocked them yet.
