One thing in all RPG's that i love using is magic. I tend to roll casters a good 80% of the time and quick agile melee the other rest. While ADOM's magic system was quite versatile with all the types of spells, pretty in depth and pretty satisfying i always felt it was lacking in certain aspects and that was the number of spells. Yeah ADOM has a decent variety of spells but i always felt it was a bit lacking and maybe JADE could improve upon that, really all there was in ADOM were damage spells such as fire ball, magic missle, and death ray. Healing spells that healed wounds disease and poison. And Utility spells ranging from knock and invisibilty to strength of atlas and wish. I'd like to see not only more types of spells but also more spells in those existing groups. Possibly some tap spells, spells that leech enemies life and maybe even lower enemy stats while temporarily increasing yours. PP taps. A temporary enchantment to a weapon such as adding +1d6 fire damage to it, or even a stun ray type effect buff for a weapon.

And the available spells were kinda slim pickings, its kinda dissapointing knowing there is only ONE ranged cold spell and it can only be cast in the cardinal directions. Maybe add a spell that does higher damage than the basic frost bolt but will only one enemy the one it strikes first, kind of like improved fireball except with no area damage. A targetable damage spell that you cast at a specific location regardless of whats in your way. I could totally see an orc sorcerer conjuring up flames from the ground underneath an unsuspecting victim, quite surprised to see flames erupt around them.

Maybe a fire spell that ignites enemies dealing damage over time. And even things as simple as casting your basic bolt spells but NOT in the cardinal directions they can follow a path just like missile weapons. Maybe a stronger version of magic missile that dosent bounce of walls. A "shock" spell that deals less damage than lightning bolt but has a chance to stun an enemy. A firebolt spell that costs less PP than firebolt but also deals less damage. And even more damage types maybe, a poison bolt that poisons whatever enemy it hits, a spell that conjures up a huge waves and crushes the enemy with both water and physical damage. A Pure light spell that while not doing a heck of a lot of damage has a high chance of blinding whomever is hit by it. A physical damage spell that calls up spikes of earth from the ground, or causes stalagtites to fall from the ceiling. A spell of pure force that can knock enemies back while damaging them. A blizzard spell, same targeting as improved fireball deals less damage and has a 50% chance to slow enemies caught within the frigid winds. Not sure how much this could be implemented I dont know how The Creator scripts his spells but I know things similar to this exist in other Roguelikes namely ToME. And maybe finally REAL pet spells that summon a friendly monster instead of hostile ones like summon monster does, whats the point of that spell lol. Conjuring up a temporary weapon or piece of armor. Summoning food when you run low. The possibilities are really endless. Even a spell that when used in the wilderness will temporarily animate a tree and have it fight for you for a certain time!

Just some suggestions, again I liked ADOM's magic there's just so much more than can be done with it than your basic, cause damage, heal damage, teleport spells.
