Overview
she is a underrated but strong aoe crowd control mage
Strengths
she is strong against low mobility heroes since she can deal damage easily and stun chain them with good positioning she can wipe out an entire team fight without even taking damage on top of that she is so good at clearing waves thanks to her w and passive you can also use the first 5 minute waves to one shot any enemy since explosion of 4 minions and her combo even can kill tanks in early game
Weaknesses
she is weak againts heroes with cc immunity and hight mobility or mages and marksmans who can outrange her
burst
she can one shot almost any hero with this build if enemy is tanky buy wish lantern over truncheon if its still isnt enough you can buy starlium sycthe since both vexana and her guardian can deal the true damage from its passive its a nightmare combo for tanks also i see people buying tough boots to her its just a waste of money she cant survive even with it and it just causes her to lack damage since arcane boots is so strong
burst
you should use these to maximize her damage if enemy is tanky you should use impure rage instead of lethal ignition
idk
if you are sure that enemy cant dodge your combo use the 3-2-1 since it allows the guardian hit an extra 1 basic attack but if someone chasing you or you are against a fast hero use your q first and follow up with w and ult to cc chain them
Best With Carmilla
i dont think i need to explain but if you need an explanation carmilla can stun the enemy and vexana one shots them also carmillas ult is super compatible with vexanas skill set they can one shot even the tankiest enemy in team fight since carmilla both amplifies vexanas damage and spreads the stun to all the linked enemy
Watch Out For Masha
masha can instantly kill vexana chase her disable her burst and stuns bc of her hp bars untargetable effects
