Certain potions and talents can increase 'sign intensity', while many others increase sign damage. The damage increase seems pretty straightforward, but what does increasing the sign intensity actually do? Those seem to be separate effects, as seen in the bonuses section of the character abilities screen.
Sign intensity seems to have a base value of 1 and the following ways to increase it:
- The skill magic intensification increases the sign intensity by +1/+2.
- The Stammelford's philter potion increases sign intensity by +1
Does it also increase damage of Yrden and Igni? Does it affect the chance of stun for Aard, the chance to immobilize for Yrden or the chance for success of Axii? And what does the value mean, how much effect does it have if I get a talent that gives me +1 on sign intensity?
