Assasin's Spell Stats On The Help Page Vs. In The Changelogs.

So, my problem is that I'm seriously confused about the spell stats on the wynncraft help page and changelogs for the assassin. The following things I'm unsure about:
1. The damage bonus of Vanish. On the help page, it states hat vanish gives 80% damage boost, however the 1.19 changelogs state that its only 70% and the 1.19.1 and 1.19.2 changes don't claim to have changed that.
Since the 1.19 changelog was released at hero beta arrival and the help page was updated on full release, might the help page be correct here?
2. Multihits damage. Same as with vanish. Changelog states it does 27% / hit while help page states it deals 30% / hit. Seems weird since all other notes of the changelog are present in the help page. Again might the help page be correct?
3. Spin attacks elemental conversions. Changelog states they're 15-20-25 while help page claims they're 20-25-30
4. Multihits fatality hit water conversion. Changelog states its 50% help page states its 30%

So what's going on here. I know the help page doesn't get updated on minor patches, but is the 1.19 changelog or the help page correct?

EDIT after doing some testing with multihits I found out 2 things.
1. The regular hits do not have any elemental conversion whatsoever
2. The elemental conversion on the fatality hit of water isn't quite 50 %, more like 35-40% at max
3. Vanish is probably at 80% from what I've seen (my tests)

 

If I remember correctly it was changed to 80% during the hero beta.

 

Okay so Vanish ,Spin and Multihit seem to work correctly as described by the help page.
Thanks for helping.

 

Its pretty much all outdated, both help page and wiki

 

This isn't true, as OP said he figured otu that it's mostly correct, also the wiki isn't edited by the official team, and it certainly isn't outdated, it has some missing parts but the framework is there
