I'm sorry for dragging this off-topic.
Ok fair enough I looked up the latest FAQ for the rulebook and saw that not every model needed it in a unit for it to benefit the whole unit (http://www.games-workshop.com/MEDIA_...nuary_2012.pdf)
It was only a FAQ though, not a errata, and not a amendment.
The USR is irrelevant because the codex rule takes precedence.
In the Eldar codex it specifically says that Karandras can only give it to Striking Scorpions.
On page 74 of the BRB it states "if any of the Codexes include one of these special rules and the rule is different, the one in the Codex takes precedence"
On page 48 of the BRB it states "the unit's special rules are not conferred upon the character, and the character's special rules are not conferred upon the unit."
I read the Eldar errata and FAQ and there is nothing that changes Karandras stealth rule or how it is applied because the codex entry takes precedence.
Now I know nothing about Telion, from what your telling me I believe his rule is different from Karandras' but I don't own a space marine codex so I have to assume that.
But I do know after looking at the FAQ rulings, the Eldar Codex, and reading the rule book I have to come to the conclusion that there is nothing to support Karandras giving wraithguard stealth or any other unit stealth.
O my god I feel so stupid, it finally clicked in my head Kelanan.
Although he doesn't
give the unit stealth....because he
HAS stealth any would squad benefit from his stealth.
I was so caught up with all the other rules the significance of what the FAQ said didn't sink into my head until I sat down and worked out all of the logic.
I'm sorry about this, I finally understand it though, even though I had to think through it for half a hour.
Thank you!
