You account will 100% get banned lol.yes u can, but for campaign and tribe tower i sugest u try without damage multiplier first, if ur normal damage only 1. don't clear the stage, u will get banned.
if u have cp at least 35k u can straight clearing to 16-28 stage, after fight boss on 16-28, don't touch the main quest or claim it. i got banned when claiming the rewards. just do daily and special boss fight to get tier 9 after that
