It's been over a week since the last one so I figured I would do the deed and post it this time. We've covered all the starters, so I wanted to bring the unofficial 4th one, the frame most new players craft as their first, Rhino!
Release date: 2012.10.25
Abilities:
Rhino Charge - Rhino charges towards a target, clobbering any in his path and goring his victim.
Iron Skin - Rhino hardens his skin, insulating himself from all damage.
Roar - Grants all nearby Warframes increased damage for a short duration.
Rhino Stomp - Rhino stomps with force sufficient to disrupt time, tumbling enemies around him in stasis.
Acquisition: Main blueprint purchasable from the Market. Components drop from Jackal on Fossa,Venus.
While I haven't played Rhino for a while, he's still a very solid warframe for newer players thanks to his Iron Skin and Roar abilities.
Rhino Charge - This abilility is pretty basic on its own, making Rhino lunge forward. With the Ironclad Charge, you can increase Rhino's armor for each enemy hit. This augment scales off of Strength and Duration. The newest instance of this mod procing will override the previous value, even if the previous armor bonus was larger.
Iron Skin - A very strong defensive ability for Rhino, essentially preventing all incoming damage and preventing forms of CC like knockdown from effecting Rhino. The update changing Iron Skin to Overguard was a pretty big buff to Rhino, especially the extra invulnerability from overguard breaking on top of shield gating giving rhino a longer grace period than most other warframes.
Roar - Rhino's "Universal Faction Damage" buff (it's additive to faction damage mods). Status effects which do damage over time can get buffed a second time from this ability, so it is worth considering modding for those status effects to make the most of this ability.
Rhino Stomp - Lifts enemies hit by this ability, and does not require line of sight. It's a pretty useful ability to use around an objective but is on the more expensive side of things energy cost wise.
For newer players trying to earn credits, he's a reasonably good warframe for the Index requiring little investment but there are some other warframes that do outshine him once enemies start to scale up.
Rhino can also be used to make a decent looking "Hybrid Fashion Frame" or an abomination. Other warframes are generally more subtle when playing around with this simulacrum bug.
Rhino! The frame that has aged like fine wine, the true rock that stands the test of time unwavered (sorry Atlas). A perfect first non starter frame for new players to obtain, giving them both the durability to withstand any challenge and the damage boost to take it down. And he never falls off like some other frames, his Iron Skin isn't the best survivability skill, but its far from the worst, and Roar (even if it is subsumable) remains the best party friendly damage buff in the game. Stomp is a decent crowd control, especially early game. Charge is his only bad ability, but even that one can be salvaged with it's augment, or just subsumed over. Fantastic warframe overall, praise be his mighty codpiece!
TIL! I knew it worked on bosses (I remember relying on it early in the game to help me with Lephantis) but the fact that it works on Eximi (or is it Eximuses?) seems like a bug, I wouldn't count on it staying that way.
