Had lately noticed my weapons downgrading in damage numbers as they were being used and leveled, so I ended up doing an experiment on the Gwylen.
To note: No changes to gear or skilltrees were made during this experiment. My spirit is at 31.
I have been playing multiplayer as the host and client while leveling The Alder, however the experiment was in solo.
Image 1. - Upon starting the game freshly, the Gwylen had attack stat at 98.
Image 2. - I tried leveling up the weapon and it leveled up normally.
Image 3. - Did a smite pull and had the active buff on.
Image 4. - After the buff wore off, it had eaten some of the damage on the weapon off. Tested leveling the weapon more and doing more smites- damage remained at 72.
Image 5. - Chose to finally restart the game and the damage went back up to 100.
Image 6. - I originally noticed the damage being drained by leveling The Alder - which is seeming to not bounce back up after restarting the game, and seems to continue downspiraling.
Changing virtues alone does nothing to The Alder, but changing pacts does.
Changing from full rank Escalda to 0 rank Tetheren takes the damage down to 13.
Changing to another weapon and back to Alder takes it back up to 56 dmg, even with Tetheren on.
Max damage is capped at 56 and will not go higher, no matter what is done.
