Consider: Kraken Slayer 1st on Shyvana
Heya, top 10 shyvana here (a few seasons ago before she got kinda mainstream, now it's around 100 and still climbing). So.. triforce feels kinda mid now that a lot of the movement speed and ability haste has been gutted. Remember when it had 25 AH, +5%MS, and +60MS for 2sec when you kill something? Those where the days.
As a shyvana, those stats really helped with her sticking/escape power. Now that those stats are down the drain, I've been trying out other builds, and as of patch 7.3, this is what I've been having the most success with.
So.. why kraken?
* Healthy mix of AD, AS, and MS. All useful stats for a growing lizard. * Passive that feels tailor-made for shyvana (atk+s1) instantly applies the extra damage. * Surprise burst. Note how much it increases in damage the lower hp the enemy is. I cannot count how many times people underestimate this burst early to midgame, allowing me to secure kills at around 20-30%hp with a single rotation of s3+atk+s1 after pretending to run away for a bit. * cheaper than triforce @ 2900 vs 3300. you are pretty much guaranteed to have kraken by the 1st objective spawn. I find that if you get unlucky early game, you sometimes don't have enough for triforce by the time you need to scramble for the objectives. * Snowball potential. Whereas triforce is the classic "ol reliable" that's pretty good at all stages of the game, think of kraken as a surprise early-midgame nuke that opens up a lot of potential kills. * Slightly better jg clear speed than triforce. Not like shyvana has any trouble clearing once you have either item, but i feel a lot faster with kraken.
Everything after the 3 item core of kraken, sunderer and greaves is situational, but you probably want to go tankier items at this point to counter whoever on the enemy team you feel might give you trouble.
Wtf? No <insert item here>!?
BotRK - Still pretty good, but i feel it competes with kraken too much with what it tries to do. The change from vamp to lifesteal also makes it so that the heal no longer works with your %hp damage from s3. You can still build this, but buy different boots, otherwise that's too much attack speed. If game goes on too long, then definitely replace kraken with this.
Triforce - See above. It's actually pretty good, in fact, you can probably replace divine sunderer with triforce. I just like the increased ability haste of sunderer(25) vs triforce(15), and it makes me tankier+better against tanks at the same time. You still want a sheen item due to your s1 being your bread and butter, so definitely don't skip out on either triforce or sunderer 2nd item.
Wtf? Why buy/use <insert rune/item>?
Greaves - I find that around 2-3 atk speed items is ideal. Atk speed from kraken + these boots is enough. And if you upgrade it, you even get extra movespeed-on-hit and some healing to help you stick around better.
Nimbus cloak - I just like movespeed, ok? You can still go resolve if you want, but I just really like movespeed now that a lot of ms from items has been gutted. You get a big boost after a flash, and a small but still noticeable boost after smite. Try to time your flash/smite with the start of your s2 to compound the ms boosts and go zoom.
Divine sunderer - You are squishy with kraken as 1st item. You want something tanky 2nd, and you still really want a sheen effect thanks to your s1. DS fills that role, and you get a big chunk of ability haste to wrap it all up. If enemy team is full ad for some reason, then iceborne gauntlet is pretty good too despite the wasted mana.
