Ivern & Senna synergy?
Im actually not sure if this would work and i'm hoping someone has, or would test it for me.
The theory is that Senna still gains wraith drops off of camps that Ivern sets free. .. I can't think of a reason she wouldn't.
The reason this would be a good pairing is because Ivern can have one of the fastest clearing paths of any jungler.
The Path You will need a ward and Teleport / Smite. (I take Unsealed Spellbook so you can swap Teleport out for more useful spells later.) Ivern doesn't need a leash so Senna goes into lane while Ivern gets set up. Ivern places a ward near the bottom most camp, late enough that it will be there by the time he has finished placing a grove on the last camp. Grove the bottom most camp, grove and smite the next buff moving up the map, and then the remaining four camps moving up the map. You will probably need to wait a few seconds for the last camp. After the top most camp has been groved, Teleport to your ward. Senna should meet you there. Groves should mature before or as you reach them on the same path up the map. Scuttle crab should also be spawning by the time you reach the top jungle and you should be able to grove and smite it.
This should give Senna 6 guaranteed wraiths, and chances are very good for her to get another off of small raptors, and depending on how krugs are calculated, maybe another there.
That's 6 - 7, 8 .. maybe 9 if you're lucky, free wraiths within roughly a minute. Just from following Ivern through your jungle.
