Description
Lunara is squishy, so you should always attack and move.
When lvl7 with Splintered Spear , Noxious Blossom > auto-attack > Crippling Spores to spread poison on enemy heroes
Thornwood Vine , Greater Spell Shield or Star Wood Spear to play safe
Lunara is good to kill bosses/objectives like the immortal, the golem etc (with Nature's Culling )
Lunara is a goddess against burst healers like Uther.
If possible, try to reach 3 stacks of poison on an enemy then switch to another target to apply stacks. But don't forget to refresh the duration on the first enemy with one auto-attack from time to time
Move, move and move again during team fight : don't forget that you are an heroic mount.
Did I forget to mention to move after attacking an enemy ?
