While I only have the 3rd edition rules (not 3.5) I was unable to find any record of a spell entitled "Spell Mantle" or any other spell that remotely has the same effects as the spell mantle series does. On a further investigation, I checked the game manuals for Icewind Dale I and II, in addition to the Baldurs Gate manuals. Once again, there were no such spells that had any related effects. I find it highly unlikely that they would add that particular spell(s) to the 3.5 edition ruleset -- when playing TableTop DND, such a spell would be impractical anyways due to there being a medly of other magic resist spells.
Quick Note: Aside from the Epic Level Handbook, the only other book I am lacking is "Tome and Blood". After being a DM/Wizard for a considerable time period however, I have the majority of the Epic spells memorized -- there is no reference to mantles in said description. If it exists, then perhaps it is in "Tome and Blood" instead?
Regardless, I was also under the impression that spell mantles were unable to negate the damage effects of any epic spell.
