When you open the skill wheel, you can see that the chance of getting Light magic is extremely low (2%)... In my opinion, in this case, it's easier to take Mass Haste in the "Attack" branch... Leadership... hmm... I would take Logistics (I really like the fast learning speed + Mass Haste... plus, it also allows you to level up faster on mobs and increases maneuverability on the map). I believe that for a Light Elf against the Necropolis: Attack (in Wing's case)... Luck, Logistics, then an alternative: Defense, Education, Leadership, Chaos/Light... there's not much else to choose from.
P.S.: Dear SERAFIM, you should specify the map size (name) and the approximate levels of the players during the battle, as this is an important factor in choosing skills and the hero (if Wing is not allowed).
Leadership is a skill specifically designed for Wing; after all, the speed aura is important.
Logistics is a good thing, but my post doesn't exclude the possibility of taking it (as a fifth skill), but some people believe that the hero can do without Logistics, taking, for example, Mages, who constantly have to play without relying on Logistics (2%).
Education is attractive, but in Wing's case, the main thing is to make the first strike deadly, so defense is not so important
