Blade Initiate is a heroic tier, multiclass swordmage feat available to characters with an Intelligence score of at least 13, who are not already swordmages, and who do not have any other multiclass feats unless the feats are also swordmage multiclass feats.
Once per day, while wielding a weapon in the light blade or heavy blade group, a character with the Blade Initiate feat can take a minor action to benefit from the Swordmage Warding swordmage class feature until the end of the encounter.
The character also gains training in Arcana.[FRPG:139]
The character gains proficiency with swordmage implements, such as light blades and heavy blades.
In addition, the character becomes multiclassed as a swordmage. The character counts as a swordmage, in addition to his or her original class, for the purpose of meeting prerequisites for feats, paragon paths, etc.[U :1/2009]
The January 2009 update added proficiency with swordmage implements to Blade Initiate.
