Any lvl for the first 3 skills, then Lyriana need to be lvl12 for rain. Btw lvl up it's easy, farm the snakes in the mountain or the white wolf near human village using stun, so you can finish them in 2 turns. Don't forgot to buy 10 attack boost from items merchant in elven village and give 5 to mc and 5 to Lyriana. For gold u farm the gobelin in gobelin cave, and u can also take advantage of the gambler in the big city tavern. The only weapons and armor need to buy are the falchion sword, fire cloak and the mithril armor. Items, potion to restore hp, magic, antidote, stone, iron pickaxe,and boost attack.
PS: About the glory hole, why no make it a trap in future update? Like when stepping inside, u walk on a glyph, and u are teleported somewere , where need fight and fuck to escape
