Idea: Stick to the titanium placed in equipment slots, but extractable ("extract all titanium" button). So the limit of titanium per character would be limited by the "magicness" of used artifacts. Therefore the mage character, who wields staff, will have more powerful spells than the others.
Now we have 2 ways to make that:
So, now, we have four kinds of titanium:
Spells are being unlocked by pairs of those:
F + F = fire spells (fireball, ignite, strength - depends on where it's put)
F + A = thunder spells (shock, paralyze, spark shield)
A + A = air spells (wind's fist, haste, knockdown)
A + W = ice spells (icebolt, freeze, frost armor)
W + W = water spells (geiser, antidote, healing)
W + E = nature spells (poison, entangling roots, regenaration)
E + E = earth spells (tremor, stun, stoneskin)
E + F = death spells (deathcoil, curse, vampirism)
Opposites:
A + E = darkness (fear, illusions, sleep)
F + W = holy (blessings, blindness)
Now every artifact can have any number of slots. For both methods (locked list of spells and customisable one) this works fine.
Now we have 2 ways to make that:
- Ingredients list - once the character learns a spell, (s)he has to equip a set of titanium to unlock it (or maybe just make it more efficient). Place where the titanium has to be equipped can rely on the kind of spell. That works if we want to set the spell list locked for all the characters.
- Unleashing - equipping titanium automatically unlocks the spell for the combination. That makes the spellbook more customizable - if player don't want to see another "warrior with flaming sword", he can equip the William's stuff with earth spells, making him the "tank" or air ones, making him the "blademaster".
So, now, we have four kinds of titanium:
- Red (fire)
- Yellow (air)
- Blue (water)
- Green (earth)
