6zoo on weapon swap * 700 * damage reduction = 528selfdamage
87% damage reduction required, to perfectly trigger lvl1 gems
1ste, you not need 87%damage reduction, you more need like 72%
2nd, he press weapon swap more then 4times per sec, therefore the selfdamage as a result from it, works for 50%effectiveniss on his cwdt lvl1 gems
3e, if he have less then 87%damage reduced, his cwdt lvl1 gems get triggered of 1000selfdamage instead of 528selfdamage, another reduced effect of cwdt lvl1 gems, 25%effectivniss left
he only use lvl1 gems, and lvl20BV
his lvl20 BV not needs 0.25sec selfdamage intervals, it just need huge selfdamage, ones per 3sec
so in the end: his lvl1 cwdt gems function at 25%effectivniss compared to other cwdt lvl1 builds
and his lvl20 cwdt gems, could aswell get sustained from 3trap-srs clicks instead of 60waeapon swaps
