@valdattaMadun please read below and I will allow you to make a choice to re-post your turn and delete the post you did if you were missing some of both of the points. If you stay with your turn I would like to give you Inspiration though, I find that bold move very inspiring.
1. I'm ignoring your sedond attack, because hadaxe sticked to mimic after the first attack and you used your one free object interaction this turn already (have no time to grab another one).
2. Also your "Giant's Havoc" feature I believe it is not your choice. You always become large when raging if there is enough space. There is so little space that if you release your handaxe sticked to mimic you will fall down the 100 feet.
