Just a list of suggestions. Obviously some of these would take awhile or are probably already planned, but still gonna say them

things you'd be silly not to include

For the love that is all good and holy please let us choose our own starting stats on characters. And also make leveling up give stats.

Chests/doors that you need a high enough stat to open. I.e. an enchanted chest you need x amount of knowledge to open or a rusty door you need so much strength to open

Option for experience/loot share. Also maybe just remove the collector merchant and just auto sell that stuff when you leave the dungeon

Training room to test your damage and maybe even fight skeletons and stuff.

things that should probably be tested

Maybe make some of the weapons that can go in the off hand able to go in the primary hand as well

Heavy attacks. hold the attack button, attack takes longer, does more damage, maybe leaves you open.

Make selecting a spell not a skill for cleric and wizard, or get rid of the q/e skill system and make it a skill wheel and spell wheel.

Make some weapons damage scale with agility instead of just strength.

Professions, such as blacksmith and alchemist

I think the current currency system is a little uneeded. There's not that much point in having money take up so much space. Just make finding actual gold coins in the dungeon rare or nonexistent.

Part of why cleric is so big is the other sources of healing are dog water. For how expensive it is to buy bandages/pots vs how little they heal, cleric kinda dominates on healing. If you do the math cleric has something like 300 points of healing base with just holy light and minor heal that can be used in the middle of combat, not even including sanctuary. PLEASE make not having a cleric viable by buffing pots and bandages and making them cheaper.

That being said, a skill that let's clerics see res tables on the map or through walls would be cool

I know you haven't balanced the classes yet but, strength>agility. Right now no matter how quick you are it doesn't matter if you don't do damage and you still get hit before you can duck out of reach again.

low priority ideas that'd take forever

Probably be worth it to look into a procedurally generated dungeon. Probably a very difficult task but just an idea.

A hub people can move around in, like a tavern or small town, where people can physically go to the merchants or a bank or their house/stash
