A friend of mine is playing a Titan Mauler and saw the "Titanic Rage" feature they get at level 14.
At 14th level, a titan mauler may choose to gain the benefits of enlarge person when she enters a rage.
And he was thinking that meant that he only got the benefits of Enlarge Person, not the penalties. I feel that when the ability says "gain the benefits of enlarge person" that basically means "enlarge person is auto-cast on you," but he says it means "I get the +2 to strength and reach, but not the -2 to dexterity or the -1 to AC and attack."
I can kinda see his side, as it says "gain the benefits of enlarge person" rather than "be affected as if by enlarge person" or something similar.
Which is correct?
