Link to the Bug: https://www2.uthgard.net/tracker/issue/4860/@/Scythe_Thorny_Shield_Skill_overwrites_Baseline_DMG_Shield

By using the After-Parry-Skills of Scythe "Thorny Shield" it will buff the Player a Dmg Shield. It will overwrite the existing Baseine Dmg Shield and run out fast. After 30 seconds it will run out, and all Dmg Shields are gone.

See also Bug #2390.

It must be valid. Why should this be wanted!?

Reproduction Steps
1. Cast Baseline Dmg Shield on yourself
2. Parry an attack and start After-Parry-Chain-Skills
3. Skill Thorny Shield will cast a Dmg Shield on Player
4. Baseline Dmg Shield will be overwritten
5. 30 Seconds later no Dmg Shield is left

Intended Behavior
System should detect allready existing dmg Shields and fail to set it on player then.

Evidence
It must be valid. Why should this be wanted!? Nobody would use these skills anymore. It has no advantage.

I see some lack of evidence. Better timer buff always overwrite the worse one.

Not sure if the style buff should be handled as a spec buff, so you got two shields active for a few seconds, but timed buffs always get overwritten by the better one. (The only annoying exception is the AOE-speed-buff from the realm speed NPC, if you got it active it will not be overwritten by the better minstrel/bard/skald speed buff.)
