Dragon nest
lv 1 add 15% dragon hp and dps
lv 2 add 20%
lv 3 add 25%
built at th9 and only working if opponent th9++
because dragon already op to th8 below and useless after th9
or my other idea
dragon hero (if hero is ruled out then i suggest making this as "villain")
alpha dragon
hp and dps dragon lv 4 + 50%
upgrade per lv 2.5% up per lv
skill summon male dragon and female dragon
male dragon speciality tank attack to alpha dragon
female dragon speciality targeting the highest defense dps targeting air
please read the bold before comment ruled out
