Bastion Information

This was added in Update 6 with the Champion System. It increases the effectiveness of damage absorbing effects by [x]%. You can put 100 Champion Points into this passive ability for a maximum of 25%.

Effects

Bastion improves shields you initiate. So if you have a shield that goes over other players, it will improve it for them too. Skills affected included:
Hardened Ward
Obsidian Shield
Blazing Shield
Healing Ward
Bone Shield
Annulment
Barrier
Brawler

Notes

With each point invested, the increase in effectiveness of damage absorbing effects diminishes. That is to say, for the first 10 CP invested, you would gain a 4.78% increase in your Effectiveness However, the next 10 CP spent (making a total of 20 CP spent), will earn you only 4.26% more Effectiveness. This is 0.52% less than the increase gained in the first 10 CP.

As such, spending just 37 CP into Bastion will already gain you a 15.1% increase in the Effectiveness of damage absorbing effects. This means you will have gained 60% of the Maximum increase possible (which is 25%) by spending just 37 out of the total of 100 CP. Therefore, beyond this point, the increase in Effectiveness received per 1 CP used is very small and not as worthwhile.
