The resist buffs and a few levels of AoM however really reduce the damage. For example the 44 DD has a potential of around 226 damage and the 34 DD has a potential of around 176 damage. Take a standard RR5 player with 26% body resist + 1 level of AoM (not every player will get this of course but its a good way to consider in those who do and the races with +2% or +3% natural body resistance) so around 29% base resist:
The level 44 DD:
With level 1 resist buff (+8% so 37%) you do 226 - 84 = 142 damage
With level 2 resist buff(+16% so 45%) you do 226 - 102 = 124 damage
With level 3 resist buff (+24% so 53%) you do
226 - 120 = 106 damage
With the highest level resist chant (+20% so 49%) you do 226 - 111 = 115 damage
With 29% "base" resist you do 226 - 66 = 160
The level 34 DD:
With level 1 resist buff (+8% so 37%) you do 176 - 65 = 111 damage
With level 2 resist buff(+16% so 45%) you do 176 - 79 = 97 damage
With level 3 resist buff (+24% so 53%) you do
176 - 93 = 83 damage
With the highest level resist chant (+20% so 49%) you do 176 - 86 = 90 damage
With 29% "base" resist you do 176 - 51 = 125
So with the combined DDs:
On a basic 26% resist rate you do 300 total damage.
On the high resist chant you do 205 total damage.
On the level 1 resist buff you do 253 total damage.
On level 2 resist buff you do 221 total damage.
On level 3 resist buffs you do 189 total damage.
On 29% resist (26% + AoM1 or natural resistance) you do 285 total damage.
Obviously there will be some difference depending on your charisma, battlesong and auq acuity levels but this is almost capped (not enough imbue points >_<) so should be around the average damage a Skald can do fully SCed.
