Apothecary is a magic affinity, support champion from the High Elves Faction, and he is absolutely game-changing for any new player and is viable right the way through the game.
The earlier you get Apothecary, the better – although due to the constantly increasing pool of champions, pulling a specific rare is getting harder and harder!
He is arguably the best rare in the game, or at the very least one of the best rares in the game.
While Apothecary does absolutely no damage (literally the lowest damage champion IN THE ENTIRE GAME!) He brings incredible support for your team with his turn meter boost, increase speed and very strong single-target heals on short cooldowns, along with a defence aura for dungeons.
Apothecary will sit in your teams for almost all content for a very long time if you get him early enough, and can even work as a tank for negative affinity content.
Build him fast, and boost up his HP – where possible you should also give your Apothecary some critical rate as his heal can actually crit!
Many people with very strong rosters, full of legendary champions will still opt to use Apothecary in their end-game Faction Wars team, so he will never be a waste to invest into, although he can do very well for you at level 50 while you are progressing.
