Note to self: write down the effects of power-ups and edit this later.
I'm not sure in what order they are activated, but when all crystals are placed you get access to special abilities that: A) Cast inferno - friendly fire possible. B) Mind blast all enemies, and C) A revival spell that heals / revives any fallen party members - I also noted that if you are revived this way you do NOT have an injury. - Gskurski
Anybody know why there's FOUR super-powa shown and only 3 to activate ? A hidden secret in the place maybe ?
If you side with the Architect he supports with a fourth special.Hugomanen 22:00, March 2, 2011 (UTC)
Possible bug Edit
This page says you get a crystal automatically upon entering the area, however I'm playing it right now and I distinctly remember the one in the locked chest (after speaking to Velanna's sister) being my first one. Also, the quest is incomplete because I only found 11 crystals, so I think that first one never spawned in my inventory.Zetaphrem (talk) 14:54, May 4, 2011 (UTC)Zetaphrem
I didn't have Velanna with me, and I missed the first one on the right as you enter Drake's Fall, in the locked chest. I had to go all the way back. Maybe you missed one too. I also don't remember getting any by default. Parochy (talk) 18:18, May 7, 2012 (UTC)
