Jungle Ivern Starting Items. Hunter's Potion > Talisman??
The downside of having plenty of time to think to myself while working overnights is that I come up with theories that I can not actually test.
Just after Ivern was released I posed a question on the Boards about skipping Jungle items.
I was met with a lot of downvotes. (Which may, or may not, happen again this time)
People were insistent on starting Hunter's Talisman because it provides "Bonus Special Experience", and they were correct, it does.
I conceited defeat and moved on.
Until now, ...
Yes, with Hunter's Talisman you gain experience faster. You also gain +150% Base Mana Regeneration, but that isn't really saying much because at level 1, Ivern has the 4th lowest total Base Mp5 (6.2 Mp5) and has mediocre Mp5 growth per level.
But, an aggressive clear with this item leaves him dangerously low pretty fast, even if you spend your remaining 150 gold on a Refillable Potion.
So here is my theory,
Starting with Hunter's Potion means that you have more charges on purchase than Refillable Potion, each charge offers mana as well which will give you more mana than you gain from Talisman, and you gain additional charges after "freeing" a camp.
Pro Tip - Unless they have changed this since I last tested it, unlike with other champions, killing/"freeing" a camp with full charges does not automatically activate a charge.
So in theory, you will not gain levels as quickly early on, but you will be healthier for longer. This should mean you can actually remain in the jungle for longer, or even have enough health and mana to gank earlier. This could even POTENTIALLY (This is the part that requires testing) lead to higher levels at an earlier point in the game.
This would also almost completely eliminate the need for a jungle item, most of which are designed to make you more effective at killing jungle monsters, and with the exception of Dragon and Baron, you do not do as Ivern. I say just skip them and go straight for a laning item that offers more useful utility.
Another small addition to this would be to sacrifice the Runic Affinity mastery, for Secret Stash.
Ivern has pretty easy access to Red and Blue buffs, so the increased duration is, useful, but may not be as necessary. Instead, by taking Secret Stash, you further increase the effectiveness of Hunter's Potion.
