Warrior deity....
 

is there any advantage to worshiping rallos zek pre-luclin? like and deity specific items?

I don't think dieties really played too much of a role pre-SoL, other than some impact on faction.

Here's a tidbit though, a Rallos Wood Elf Warrior is KoS to the guards in Kaladim =p

You might not be KOS to Kael in Velious. Other than that I don't know.

Rallos Zek ogres (maybe trolls too?) are not KOS to Kael by default in Velious. IDK about other race Rallos worshipping WARs though.

This can't be true. My RZ halfling warrior did a lot of stuff in Kaladim.

Maybe Halfing natural faction offset the Rallos Zek natural faction?

Or you just happened to kill a ton of goblins/orcs or something before venturing inside.

You sure about that? What NPC was kos to your wood elf warrior of rallos zek?

Lol I remember my newbie rallos wood elf being killed by guards at xroads on my way to turn in cb belts, needless to say I ended up selling the belts.

Warriors have some really interesting choices for deities. I would go with a wood elf who worships Erollisi Marr.

No advantage to not going agnostic other than starting off non-kos to 2 Velious factions if you go Rallos Zek (think you need to be Ogre too).
