Castle Clash: Don't be FOOLED!! Buying Essence Packs will cost you more Merits to get Skill EXP than Shard Packs. 1) One Slime Essence Pack gives you 10X100=1000 Skill EXP and costs you 550 Merits. If you buy 5 Shard Pack1's, they will give you 1000 Skill EXP and cost you only 275 Merits. 2) One Crystal Ooze Essence Pack gives you 2X600=1200 Skill EXP and costs you 600 Merits. If you buy 2 Shard Pack2's, they will give you 2000 Skill EXP and cost you only 500 Merits. 3) One Gelatinous Champion Essence Pack gives you 1X3000=3000 Skill EXP and costs you 1500 Merits. If you buy 1 Shard Pack3, it will give you 4000 Skill EXP and cost you only 900 Merits. Don't forget that you can ALSO use Shard Packs to hire Heroes 😉. #castleclash by castleclashpro
