Whoops, i play on pc with control pad so mouse wasn't on my screen while playing, i didn't even notice it was there when i uploaded it lol.
1. It's the alternate Quen sign (hold RT on xbox pad)
2. Put 2 ability points into sustained glyphs under the Yarden sign to put multiple traps down and get the alternate Yarden sign (hold RT)
3. It's the alternate Igni sign (hold RT)
You have to unlock the alternate signs with ability points first obviously.
