So it's a relic that works well with lj?Phase gets additional damage for attacking from hidden based on your hiding and stealth skill so you would get half of that additional damage (25 extra I believe). The real benefit of phase is in equipping a heavy hitting weapon and having double strike ready if you have it. On a good roll I have hit for damages over 800 (combining the phase, swing and double strike that all hit at the same time). The key is big weapon for phase.
