Melee weapons have scaled leech maximums based on weapon speed. This applies to non-imbued leeches, as imbued leeches cap at 50 regardless of weapon speed. I do not believe that scaled leech caps ever apply to thrown or archery weapons, but someone please correct me if they have seen something else. These figures are projected based on some experimentation. It appears that the equation for the increase is as follows: X/2 * 50 = Max Leech where X is weapon speed. This means that leech maximums cap at 4s.
If anyone has seen definitive information on this subject, please let me know.
2s 50%
2.25s 56%
2.5s 62%
2.75s 68%
3s 75%
3.25s 81%
3.5s 87%
3.75s 93%
4s 100%
As an aside, if you have a weapon with a scaled leech above 50 and imbue it to add increase weapon speed, it will adjust the leech downward. I have not done significant testing to determine the math behind the adjustment.
