Based on the description SE gave PGL on the official site, Square claimed that PGL had two stances. A defensive stance and an offensive stance. I couldn't find any abilities other than Light Strike.
The description reads:
"Attack with your hand-to-hand weapon, dealing blunt damage. Increases physical defense and evasion."
Now, the description says it doesn't stack at all, so it seemed like a lackluster ability only to be used when it wears off. But I questioned, "What if it does stack?" I started to use Light Strike only and eyeballed a noticeable evasion increase, and that's what inspired me to test this. So like any good theory crafter I got out a notepad, and took down some notes. Here are my findings.
Highlander. 11 PGL
41 STR, 60 VIT, 44 DEX, 40 INT, 60 MND, 60 PIE.
Evasion 118. Defense 123.
For the sake of the test, I couldn't completely reach 100 on both defense and evasion, so I got as close as I could.
Target: Thistletail Marmot (All Blue)
Test Number 1:
Using Heavy Strike only to gain the attention of the mob.
Total attacks: 208
Evaded: 32 or 15.38%
Missed: 16 or 7.69%
Total Damage: 4064
Damage taken overtime per hit: 25.4
Maximum Damage Taken: 36
Minimum Damage Taken: 23
Average WS Damage Taken: 42.64
Average Parry Damage: 11.11
Test Number 2:
Using Light Strike only once it wore off.
Total Attacks: 212
Evaded: 36 or 16.98%
Missed: 18 or 8.49%
Total damage: 3646
Damage Taken overtime per hit: 23.07
Maximum damage taken: 36
Minimum damage taken: 23
Average WS Damage Taken: 41.61
Average Parry Damage: 10.98
Test Number 3:
Using Light Strike in succession. 2 Second in between each attack after I ran out of stamina.
Total Attacks: 210
Evaded: 44 or 20.95%
Missed: 24 or 11.42%
Total Damage: 3038
Damage Taken Overtime per hit: 19.98
Maximum Damage Taken: 37
Minimum Damage Taken: 23
Average WS Damage taken: 43.78
Average Parry damage: 10.61
Conclusion: Light Strike does have a more potent effect when stacked. Minimum damage is the same across all test. The Marmot missed more and I evaded a lot more when I used Light Strike one after another, thus bringing my total damage taken overtime a lot lower.
So for all those evasion tank PGL out there, stacking Light Attack will reduce your total damage overtime.
I'll try and retest this once I gain more ranks and see if I get similar results. It may be a small sample size, but it was enough to know that Light Strike does stack.
