Important: I am well aware they have their own idea for the Runemaster, I just wanted to share a few Skill/spell ideas I had. Also, the numbers I am using are simply to help convey the idea of the specialization.
I will reply with abilities, which will contain Specialization and finish with a few relevant passive nodes that are tied to its specific mechanic. All will be added in this post with Spoilers.
Mana reserve mechanic:
Reserved ability hold unto a set amount of mana. reducing your available mana. This does not reduce your maximum mana. When mana becomes unreserved, the mana is lost and you can regain it as normal.
Mana Shield (Rune of Protection):
Reserver 10% of you maximum mana (skill disabled if you have >10%)
Gain the same amount as Ward
Upon reaching 0 wards your mana becomes unreserved.
- Powered Shield (0/3)
Increased reserved mana by 5%
- Improved Shielding (0/2)_____________ Reflective Shield (0/6)
Ward gain is increased by 100%______ 2% DMG ref while Mana shield reserves mana
- Blast Shield (0/5)
When Mana shield becomes unreserved, deal damage around you equal to 30% of lost mana
- Area Effect (0/5)
Increase AoE by 20%
- Elemental Protection (0/5)
Gain elemental resistance equal to 20% of reserved mana
- Necrotic/Void/Poison Protection (0/4)-(0/4)-(0/4)
Gain XXXXX resistance equal to 25% of reserved mana
- Armored Shielding (0/1)
Gain armor equal to 100% of reserved Mana
- Maybe a Third option?
Gain something on Cast or When Mana is unreserved. Feel free to help
