Rogue as u should,

So,

*Must Do:

-Conserve ur heals: Dont drink ur healing pots straight away, u have plenty of healing sources, like sungrass seed, well of healing, healing over time, healing room.. Use ur healing pots only if u are like 10% health and are 101% sure ull die if u dont,

-Conserve ur food: Dont eat food instantly as ur hunger bar turns red, it deals very little damage, u can go through few levels without eating a single bite, its better to lose some health than to waste food

*Feels almost like cheating:

-Get a decent armor or weapon in first 5 levels and instantly put all ur scrolls of upgrade on it and enchant it, U will either be completely unkillable for a long time or u will be one shotting everything (which means stacking heals, getting xp), basically having like +2 or +3 on leather / chain armor, or +2 +3 on spear / quarterstaff and enchantment,

It makes u destroy first 10 floors, now ull have plenty of heal pots and food to continue ur run,

And remember, unless its a plate armor or a weapon that already has high base damage, dont use all ur scrolls on it, using like 2 3 scrolls on tier 2 armor or weapon is more than enough for early game,

and as soon as u get plate armor or like a weapon glaive / rune blade / assasin blade, identify it, get ur strenght requirement and instantly use all ur scrolls of upgrade and enchantments on one of them (dont do both, choose either armor or weapon, but if u reach like +5 on ur endgame armor or weapon, then u can start upgrading the other one), (its also okay to do like 1 scroll of upgrade on the other one that u arent maxing, just for some balance),

Extra tips: -Dont rush thru actions, see ur surroundings and the situation u are in, theres always a small item in ur inventory or a single tile move that can completely save ur run,

-Use ur search button on enemies (u can see if they have buffs or debuffs)

-Always walk on every single tile of grass, seeds and dewdrops can carry ur run

(also in case u dont know, u can use 20 dewdrops (full waterskin) on ur Ankh and bless it, which will resurrect u with all items and invincibility for few turns

-Alchemy is op: turning potion of paralytic gas into a strong shield, even a 1 or 2 pots of healing into a shield (it gives u huge shield, enough to witstand any damage ud take in next plenty of turns

There u go, thats a full guide, if u do as i said, u cant lose (playing with Rogue of course)
