Ridley's Cohort said:If a high level Wizard wants to shape an area through which he cannot cast spells at his enemies, why exactly should I object to this?
Sure it is a cute trick with which to catch the unwary, but it is not ultimately very powerful.
I mean no offense Ridley's Cohort, but I think is a very naive statement. Cute trick!?!?!
Higher level game balance is completely dictated by equipment, nevermind the fact that A-MF hoses any pure spellcaster. Consider even just one minor aspect of higher level play: 3-D combat. Past level 10, aerial combat becomes routine. For most PCs the only way to gain aerial mobility is with spell access (barring the occasional gryphon or pegasus mount). A wizard with this ability could cast the following spells: fly, protection from arrows, shaped A-MF. This panel renders him virtually invulnerable to anything PC's can throw at him (literally and figuratively). If the PC's try and get within melee range their fly-type spells will fail and nothing they do at range will be very effective (barring the deepwood sniper of course). I of all people am hesitant to use this language, but a wizard using such a tactic would RAPE a party of PCs.
In contained quarters (like the underdark) this tactic is all the more devastating. Picture this: shaped A-MF with the wizard casting something like an earthquake (pick you pertinent spell - anything to cause a cave collapse) while the wizard has a contingent gaseous form or something similar.
The possibilities are endless.
