the thing with -1pc ,is that u cant get -7pc(few super tortoises upgrade it) when u dont have already -1pc and that can be done only by blessed rebing ...
i dont see a point in telling that -1pc sux ,u kno its just only way u can have -7 and -7*6=-42% that means when u get 1000 dmg normally then u will get only 580 with full -7
(or 510 when u dual hold)
and when u get urself full-7 and full 2soc super torts and dual: (-7%)*7 + (-6pc*14) = -49% + -84% that means when u normally get 1000 dmg u will get :
1000*51%*16% = 81,6 and that IS something!
doe im not sure hows the case with a cap at - 90 % of whole reduction, all i kno is that reductions from bless and gems add independently one after another
(not like 49%+84%=-133%, but 84% of (100%-49%) =-91,84%)
