NOTE: if you wish to save an umbra forma, using a rank 0 Umbral Fiber will work just as well and that way saves the need for the forma. If you wonder where you can get a rank 0 umbral fiber you can buy one at cephalon simaris' shop at any relay.

INTRODUCTION
This [Rhino] build requires a very high investment but the result is a 526% Strength, 226% Duration and infinite energy (12 energy regeneration per second). Providing the strongest weapon's platform i currently play. A menace to bosses/archons/acolytes etc.

__
ARCHON SHARDS
1x Tauforged emerald (+3 Corrosive stacks) since you would usually run corrosive on your weapons in combination with viral from Nourish.
1x Tauforged Azure (75 max energy) since we dont use [Flow] and need a baseline energy for casting buffs at 45% efficiency.
3x Tauforged Crimson (15% strength) because Roar goes REEEEEEEEE.

__
MODS
First of all, as stated before, there is no need for two umbral formas, however there is a need for 3 Umbral mods. These give together 77% STR from [Umbral Intensify], 25% STR from arcane Bellicose (1036 health) and some armor to beef our Iron skin.

Energy nexus works great with Nourish (especially at 500% power strength) giving us ~12 energy/sec which makes energy orbs completely irrelevant.

Exilus slot is completely free, i chose to use it for extra Parkour speed for insane mobility.

Aura is also free, i prefer Growing power for the extra strength.

__
HELMINTH SUBSUME
Nourish, its Nourish. Infinite energy + infused Viral to our guns.

__
FOCUS SCHOOL
Madurai is the best in slot option, giving 40% STR and 50% casting speed after 2 slingshots while in operator. This works great with [Rhino] since its used in rotation per rebuffing.

__
ARCANES
Going for Molt augmented + Arcane Bellicose yields 85% Power strength.
Bellicose' impact isnt as great, and you may replace it for any other weapon buffing arcane of you choice.

__
ALL IN ALL
This build is crazy investment but i can guarantee this is the best you'll ever play as [Rhino]. He's pretty much soloing anything and everything without a scratch or any need for energy or resources. completely self reliant.

how to play?
1. go into mission and start at 50 energy. [Energy Nexus] should get you to the sweet 78 energy point to cast Nourish in about 10 seconds since starting the mission.
2. Activate madurai buffs and cast Nourish, now your energy should spike SUPER fast, enough to cast Iron skin and Roar in a matter of seconds. I personally use an energy pad at this point cuz im impatient, but anything works.
3. Cast Iron skin and Roar.
4. At this point you're done, start killing anything you see and rebuff yourself as needed.

How does [Rhino] get 526% STR?
baseline 401% STR from Mods + arcane bellicose + 45% STR from archon shards.
60% from molt augmented.
40% from madurai focus school.
25% from Growing power.
Total power strength at mission -> 526%. this puts ROAR at a whopping 263% Damage increase.

Best in slot weapons for this setup:
Pretty much any weapon, but i find general gameplay (that includes EDA/ETA) to be best cleared using Ocucor (Corrosive+Heat) for 98% of enemies, Burston (Corrosive+cold/Corrosive+Blast for incarnon) for bosses/acolytes and [Praedos] for the Parkour speed it gives.
Also using a companion that can supply [Tenacious Bond] and [Reinforced Bond].
