The protector’s strike bug is still here ! During last tournement i was surprised so, with a friend, we have test during 1 hours how to reproduct this one. And, it’s really simple.
If you try to dodge after the first block with Protector’s strike, you become invulnerable during 4/5 seconds (And you do all you want).
In Theory you can be invulnerable during 5 seconds all 15. But with the dodge, and the block it’s more 5 second of invulnerability all 11 second.
