Do you have enough stamina? Do you have enough Health? Do you have enough Attack? Do you have enough Defense? Have you tried asking your friends for help? Also, wait more than two minutes before begging for a reply.
ok boss attacks: you need good attack defence and health and all this together will do good boss damage.. !! not only high health !! also than higher level boss is than stronger will be and u will need to do more attacks on higher level bosses. also unlocked power attacks will give you do more damage to your or friends boss if you go leaderboard you can see who kill lots boss there and send them invites so after they join just send them private message help kill boss and they will help hope this helps
