Metamagic class feat for Spellcasters

[4Luke4]

This component adds the NWN-ish class feat Metamagic to spellcasters (all but Bards, Sorcerers, and Shamans).

Metamagic feats change some aspect of spells as they are cast, making them more effective or circumventing some restrictions.

• Quicken Spell
  Quickened spells can be cast instantaneously, making them invulnerable to interruption.
  Quickened spells consume spell slots four levels higher than normal.

  • If you want to quicken a level 1 spell, all memorized spells of level 5 will be decremented by 1.
  • Wizard spells of level 6+ cannot be quickened.
  • Priest spells of level 4+ cannot be quickened.

• Empower Spell
  All variable, numeric effects of an empowered spell are increased by 50%. Empowerment does not increase spell duration.
  
  An empowered spell consumes a spell slot two levels higher than normal.

  • If you want to empower a level 1 spell, all memorized spells of level 3 will be decremented by 1.
  • Wizard spells of level 8+ cannot be empowered.
  • Priest spells of level 6+ cannot be empowered.
  • As a completely artificial example, an empowered Magic Missile will deal 1d6 + 1 (instead of 1d4 + 1 ) points of damage.

• Extend Spell
  Extended spells have their duration doubled, lasting twice as long as normal. Spells with a duration of instantaneous or permanent are not affected.
  An extended spell consumes a spell slot one level higher than normal.

  • If you want to extend a level 1 spell, all memorized spells of level 2 will be decremented by 1.
  • Wizard spells of level 9 cannot be extended.
  • Priest spells of level 7 cannot be extended.
  • As a completely artificial example, an extended Web will last for 2 turns (instead of 1).

• Maximize Spell
  
  Maximized spells apply all variable numeric effects — including damage, number of targets, and so on — at their maximum values.
  A maximized spell consumes a spell slot three levels higher than normal.

  • If you want to maximize a level 1 spell, all memorized spells of level 4 will be decremented by 1.
  • Wizard spells of level 7+ cannot be maximized.
  • Priest spells of level 5+ cannot be maximized.
  • As a completely artificial example, a maximized Magic Missile will deal 5 (instead of 1d4 + 1 ) points of damage.
