You can use food to heal, you can pair that with the arbalest heal right at the end of battle to heal a bit more. Going with very low light is perfectly doable but it's mostly to get loot and it's significantly more taxing and dangerous.

One of the first thing should be to always have torch at more than 75 (brightest), that means more dodge, hence less heal, no stress maluses, and most importantly more surprised enemies which is very interesting to negate the needs of heal by nuking the stress dealers from the get go. Generally, good stunners (Plague Doctor, Houndmaster for instance) can efficiently replace healers because in the end, an enemy stunned is an enemy not damaging you, therefore less need for heals. Basically, especially in the Ruins as Justice pointed out, having a Jester and a Vestal is almost detrimental because you're going to be out of damage as those classes aren't able to put anything relevant downrange, you're therefore limited to only two heroes at best capable of doing damage which is pretty short.Ĭrusader is indeed one of the best class in the game because he can do pretty much everything, managed well he can hit any range, heal, stress heal, stun, take the damage and deal it.
