For instance, I was using an armor that gave +20% Igni intensity and then I attached to it a Superior Igni Gliph (another 10%). The third effect, incineration, is the easiest of the 3, imo, because there's so much you can do to increase your Igni's power. When I was going for this I made sure that the little words "bleeding" and "poisoned" popped up above the enemies, that way I knew they were under the respective effects. Keep in mind though that (I think) the effects won't be cause automatically (since it's a "chance") nor at the same time/hit. That way you'll have a single blade that will cause 2 out of the 3 effects needed. You must attach 2 superior Morana runes to it (+5% chance each to cause poisoning). I've mentioned in other solutions about the great TIR TOCHAIR BLADE. That's okay though for if you do what I'm about to suggest you will end up unlocking the achievement just like I did. There are 52 achievements with a total of 1000 points.Easy, although in this GotY edition you can't use the Xbox Dashboard thing to keep track of how many you've successfully performed, unfortunately.

Plan on spending a lot of monster slaying fun with Geralt when the game hits consoles and PC on May 19, 2015. Just to give you an idea how immense, the two planned expansions for the game THE ADD-ONS are said to take 30 hours to complete. Boasting some of the strongest graphics on any console on which it’s published, The Witcher III promises an immense game world.
Based on a series of novels by Polish author Andrzej Sapkowski, the games follow Witcher (monster hunter, basically) Geralt of Rivia as he travels the land, slaying beasts, completing quests and the whatnot.
