Nightblade Elusive Crit Multi

When gaining Elusive via another way other than Nightblade Support (e.g. Assassin's Mistwalker, or Withering Step), the skill Nightblade Support is linked to gains only 100% or so Crit Multi, compared to the almost 500% extra you get if the skill it's linked to activates Elusive. Based on the reading of Nightblade "Elusive from Supported Skills Also Grants 132% to Critical Stirke Multiplier for Skill Supported by Nightblade" it sounds like if you gain Elusive via any other means you shouldn't get *any* Critical Strike Multiplier.

Based on my testing with Assassin's Mistwalker and the 40% Elusive Effect from 'From the Shadows', with a level 17 Nightblade, I go from 267% Crit Multi -> 752% if the skill it's linked to activates Elusive. If another skill activates Elusive (using Assassin's Mistwalker's Elusive on Crit with Shield Charge, unlinked to Nightblade), the skill that *is* linked to Nightblade goes from 267% -> 367%. Or 267% to 375% if activated instead by a level 11 Withering Step. Your crit multi elsewhere is unchanged, of course.

Unless I'm misunderstanding some interactions, it seems to be in these situations, the skill linked to Nightblade should not be gaining any Crit Multi unless it's the skill it's linked to that's activating. But, since it *is* gaining some crit multi, it should be gaining the full 485% from all the Elusive effect, rather than just the base 100% or 108% (I assume withering step gives slightly more due to the Elusive effect from the gem?).

If I unallocate 'From the Shadows' (40% elusive effect) then as expected I only get to 683% crit multi instead of 752% when the skill linked to Nightblade support is activating Elusive, but when say a Shield Charge crit activates it, it goes to 351% and if Withering Step activates it, then 359%. Which I'll be honest is even more confusing I figured those last two would be unchanged. So yea, idk why the skill linked to Nightblade is gaining any crit multi if you acquire Elusive from other means, but since it is, I don't understand why it's not the full ~500% lol.

Would love to know if I'm just missing something obvious. Thanks
