The flame and frost zombie loaded correctly on my server, but they did not work as intended. When I first used "e" to use the skill, it just said I was on cooldown and when I used it once the cooldown was over it said I was on cooldown again. I held it down to see if it would help but it ended up lagging the server because it messages you 4 times per action and if you hold it down it lags the server.
