I have been unable to update the synergy spreadsheet, due to some very confusing, "in game" testing results. I do not speak or read Korean, so it can be very challenging. I am currently on server #3, If any other, English speaking players want to help me, test some, "in game" synergy mechanics, please post here.
Some interesting observations:
There are 59 total abilities in the game.
28 Debuff Abilities
28 Buff Abilities
3 Special Stacking Abilities
19 Debuffs have cross tree synergy
3 Buffs have cross tree synergy
2 Stacking abilities have cross tree synergy
And, just in case, your thinking, who cares about this synergy crap................. let me explain.............. A very small, well organized group, with "complementing" synergy, can completely "steamroll" a much, much larger group.
