Much to my chagrin, I recently discovered that there is not a mount with +4000 Lifesteal which miffs me as a Templock atm. So this got me think on mounts and with a friend of mine who is an artist we came up with some ideas and concepts but no actual art at the current moment.
Epic/Legendary: Wraith(spirit)/Undead(skeletal)/Living (Black) Winged Unicorn (Alicorn/alacorn, latin for winged horn), the living one would be called the Resurrected Death Wing.
+2000/+4000 life steal respectively.
Death Wing: The Combat ability for the Legendary variant would look like the Alicorn flies in from above and lands in the middle of combat. Once it lands it charges a necromantic spell on it's horn before rearing up and then stomping the ground, discharging it's magic. The magic would result in a shock wave of life stealing energy, before the mount flies away again.
Legendary: Celestial Pegasus(Or maybe a Celestial Alicorn?)
+2000 Deflect/+2000 Movement
Celestial Agility: Your mount flies over your head/combat area, blanketing the area in the brilliance of the sun and grants a temporary buff (30-50%?) to movement/speed(animation as well). Pressing the ability again will cancel the ability early and result in an AoE Blind.
Legendary: Lunar Pegasus(or maybe a Lunar Alicorn?)
Lunar Balance: Your mount flies over your head/combat area, blanketing the area in a veil of shadows/darkness and grants a temporary buff (30-50%) to deflection/speed(animation only). Pressing the ability again will cancel the ability early and result in an AoE Slow effect.
