I don't really have spells to add but I can classify how I think the spells should be implemented.
Heroic (1-10)
Skill bonus spells: (become "swift" (or whatever the equivalent is in 4E) actions with 1 round durations and give +20 to the skill check. Knock (open locks), invisibility (sneak), detect lie (sense motive), true strike (BAB), identify (spellcraft), find traps (search) etc)
Save or suck: (this is really tough: sleep, color spray, charm person, hold person, and the list goes on, are all very ingrained in the system yet seem very powerful)
Paragon (11-21)
Skill bonus spells: now with a longer duration
Save or really suck: (stat damage, unconscious,
Fly: (poor maneuverability, actually grows wings or something)
Dimension door:
Plane shift:
Regenerate:
Speak with dead:
Detect alignment:
Epic (21-30)
Negate class spells: (mind blank, true seeing,
Fly: (perfect maneuverability)
Save or die or lose: (disintegrate, implode, slay living, flesh to stone, feeblemind, polymorph [baleful or any object]){I like the 2 stat damage a round until X happens}
Teleport:
Scrying:
Raise dead: (resurrection, reincarnation)
Gate:
Wish:
Anyone else want to add their spells to this list?
