I main Captain Phinn, and over time i have devised a strategy that i hope you will use, if you decide to give it a go, here is how you can build/use it

First off, always start with -Sprint Boots- and -Oak Heart-. you need to get boots to get your speed up to a regular characters speed, because Phinn is slower than every other character. The Oak Heart is to get some health and start building toward -Fountain Of Renewal-.

As Soon As possible, and at least by the Ten Minute Mark, you should, if you and your jungler have been working efficiently, have (in the order you need to build them) -Fountain Of Renewal-, upgrade to journey boots before getting a -Crucible-, then buy -War Treads-, finally get an -Atlas Pauldron-. REMEMBER TO ALSO HAVE VISION SET UP AT THE GOLD MINE BY NOW, for other vision, put scout traps under the Treeant closest to the gold mine on your side, (they will be less likely to find it), on the far side of your jungle shop bush, and on the top left corner of you Gold Miner Bush.

At late game, or by 15-20 minutes, you should have your full build. this will consist of earlier said items, but for your final 2 items, get first a -Contraption-, this item is essential to any suport captain build as it gives you a regenerating amount of scout traps and/or flares. use these to keep up heavy vision to prevent being jumped and give your team the advantage. Your final item will be a -Nullwave Gauntlet-. This item, when tapped to activate, allows you to select one enemy hero for targeting, you will launch a homing shot after that hero, disabling their items and dealing 15 Percent of your max health + 100 in damage to that hero (a total of 751 Crystal damage) And there you have your complete Unstoppable Defender Phinn build.

Notes<><><><><> when you want to heal your team with fountain of renewal, if there are no enemies currently engaged with them, simply use the fountain by itself, IF YOU ARE ENGAGED IN COMBAT, use your crucible first then immediately use fountain of renewal. this gives your team a shield to soak up damage while the fountain restores their health.

NULLWAVE GAUNTLET- primarily use this to disable the enemy captain for 5 seconds, but it is also very useful to last shot a running away enemy.

ABILITIES- when you use Phinns Forced Accord, immediately use his Quibble on the area they are in, this will stun then allowing you to use your Polite Company to further drag them toward their almost certain doom.

PROTECTING YOUR TEAM- ALWAYS BODY BLOCK, if there is a, example, Celeste or Kestrel Ult headed toward a team mate, use your war treads to get them out of danger and body block it if necessary.
