Armor and Enrage are useful buffs. However, I noticed something that seems weird, and though it's relatively minor, I also think minor adjustments would make both abilities a little less crutchy.
So both buffs can stack up to 5. When you read the description of the buff, each stack offers a 25% increase to damage output (for Enrage) or decrease to damage received (for Armor). This means that each buff caps at a total of 125% benefit. In the case of Enrage, this means at a full stack you are dealing over double damage. For armor, this means at stack 4 you've already reached 100% damage reduction, so 4 stack and 5 stack for Armor are exactly the same thing (which feels redundant). I feel like both of these abilities should have each stack reduced to 20% buffing. This would make it so that achieving a full stack of those buffs would correlate with a 100% benefit, which makes more sense to me than going over 100%. This would especially be useful for balancing armor, because it would mean you'd need a 5 stacks to completely nullify all damage instead of 4. I think this would balance both of these buffs in a beneficial way, especially Armor, as getting a stack of 4 Armor yields the same result as the Invincible buff.
Or, alternatively, just change Armor's buff to a 25% increase to defense (per stack). This would allow it to keep it's damage-reducing qualities without overlapping qualities with Invincible, and I would be fine with getting a 125% bonus to defense. That would be more in-line with Enrage's 25% increase to damage per stack, and would make Armor more unique compared to Invincible when at full stacks.
