As a guild we're only doing this for the gold. We really don't care about rankings but we have realized we cannot get past the current dungeon without a team approach.
We have started to work towards a coordinated attack approach with 1 player buying the boosters and everybody attacking at the same time. We see that does have some benefit but we have seen some things which raised some questions.
How often can a single player buy a booster? We think it might be 72 hours but are not sure.
If you buy a booster before the time out (assuming there is one) do you just loose the gold and diamonds?
Can a team buy boosters more than once a day as long as different people make the purchase?
The bombs are not affected by the crystals so we have been using them on the boss while we attack the crystals. Does this really matter since there is a total HP for the combo of boss and crystal?
Other than boosters and coordinated attacks is there anything else we as a team can do?
Any and all help will be appreciated.
