its gunna be the only achievment barring mass exodus i need when i finish, and possible the siding with mages/templars ones. im at the start of act 3 and sebastian is rite in the middle of friend/rivary, im guessing theres no chance to get the achievment before the end, however, is it worth starting a new game, what i was gunna do was do the last 3 mage/templar quests and then re load my save to get the other. i tried to get the rivalry by doing the glitch listed on xbox360achievments.org but it wont work.
so, shall i start a new game, and go all the way through just to get this? question is, if im gunna start a new game, just for sebastian, which should i side with when i play to max out friendship/rivalry, because ill do the opposite now, on my current playthrough. or, shall i just reload my save and get both now, and just play through till i max him out.
also i visited the chantry at the very start of act 3, and the book is there on the pedestal, but i cant select it or pick it up!
