Your ray spells can affect an additional target
You can cayse any ray spell to fire one additional ray beyond th enumber norally allowed. The additional ray requires a separate ranged touch attack roll to hit and deals damage as normal. It can be fired at the same target as the first ray or at a different target, but all rays must be aimed at targets within 30 feet of each other and fired simultaneously. A split ray uses a spell slot two levels higher than the spell's actual level.
You can simultaneously cast a single spell twice. Casting a twinned spell causes the spell to take effect twice in the same area or on the same target simultaneously. Any variable characteristics (including attack rolls) or decisions you would make about the spell (including target and area), are applied to both spells, with affected creatures receiving all the effetcs of each spell individually (including getting two saving throws if applicable). A spell whose effetcs wouldn't stack if it was cast twice under normal circumstances will create redundant effects if successfully twinned (see Combining Magical Effetcs, page 171 of the Player's Handbook). For example, a twinned charm person doesn't create a more potent or long-lasting effect, but any ally of the target would have to succeed on two dispel attempts in order to free the target from the charm. As with other metamagic feats, twinning a spell does not affect its vulnerability to counterspelling, so a single successful counterspell negates both instances of a twinned spell. A twinned spell uses up a spell slot four levels higher than the spell's actual level.
You can cast a spell to maximum effect without special preparation.
Once per day, you can apply the effect of the Maximize Spell feat to any spell you cast without increasing the level of the spell or specially preparing it ahead of time. You can still use Maximize Spell normally if you have it.
