Sea Obis and Elemental Siphon

[MaachaQ]

I just got my first Obi today (never really felt the need to get them before now) and was wondering if anyone knows if these would enhance the effect of Elemental Siphon for SMNs. Don't get light weather often (unless in Temnos or other special zones), and Light day is a ways off, so I can't test on my own atm.

If these obis do make Elemental Siphon better, I'll definitely get off my butt and go farm organs for more of them, especially the Wind and Dark Obis, which are the spirits I most often use for elemental siphon.

Pretty sure they factor in day/weather 100% of the time anyway. So no they don't do anything for siphon.

I can't imagine they have an effect. The Spirit exists outside of the player's equipment, no different than trying to use Sniper Rings to give your Avatar better accuracy.

But yeah, Spirits get the day/weather bonus 100% when it comes to Siphon.

Just echoing what the others have already stated. The only things that I've seen to increase Elemental Siphon's amount of MP restored is the day of the week, weather, and believe it or not Summoning Magic (and I have tested this because it was originally just a theory). In order to test it I performed ES with Carby Mitts on and it returned less mp (same day same weather) than when I put on my Summoner's Bracers for the next ES 5 minutes later. Hope that helps!

This is very true, as I'm levelling SMN and not having the skill capped whenever I get one skill the MP return from syphon goes up by 1-2 points.
I also noticed that weather can override day bonus: es. on watersday with thunder weather, if you use water spirit you have a chance for -10% mp return, yet the opposite does not seem true, es. wind weather and iceday using Air spirit.

Ickywiki description:

(Summoning Skill - 50) x (Bonus%) = MP restored.
1.10 for matching day or weather,
1.20 for matching day and weather,
1.25 for matching double weather, and
1.35 for matching day and double weather.
Example: Thunder spirit on Lightningday with thunder weather and 310 summoning skill: (310 - 50) x (1.2) = 312MP.
Using a spirit that is weak to the day/weather will incur a penalty to the amount of MP obtained equal to the inverse of the bonus for matching. (i.e. Using a Thunder Spirit on Earthsday will get you .90 your base MP returns. Using a Thunder Spirit on Lightningday with single earth weather will cancel out and you will receive the base.)

Is Summoning Skill checked when you summon, or when you use Elemental Siphon?

at the time of Elemental Siphon use.
