Somewhat. It's capped around 50 dmg, though bleed feats ignore this.

No. The longer the execution, the more health you gain - in theory. Executions can be weird but this is the general case. The max HP gain from an execution is 50 HP.

Yes.

No, with exceptions. Hyper armor can eat through deflects and Black Prior can flip some heroes' deflects.

Yes, though if you are bled while in Revenge, it still applies and can still be there after you exit Revenge.

Yes.

No, though killing minions adds points for your team with +1 point per minion.

No, it does 60 damage. However, it instakills minions.

BP can flip any attack except for projectiles, guardbreaks, and Nuxia's traps. His flip has an input window of 100 - 400 ms making it possible to flip very quickly. BP's notable flip possibilities are:
- Virtuosa's Riposte
- Hitokiri's Senbonzakura insta-kill feat
- External attacks
- Ledge attacks
- Other BP flips

When Virtuosa enters a Posture stance, she gains persistent dodge enabling her to dodge almost any attack including bashes and projectiles. She cannot dodge undodgeables or AoE feats like Fire Flask. This stance can only be countered with guardbreaks and undodgeable attacks.

The light attack speed from neutral for all heroes is 500 ms. For some heroes, their light chain attacks and light finishers are 400 ms as listed below.

Peacekeeper, Berserker, Highlander, Sohei, Nuxia, Tiandi, Shaolin, Medjay, Ocelotl, and Virtuosa.

The hero with the second fastest light attacks is Gladiator with 433 ms on his top light chain.

Highlander. (Wavedashing. Look it up.)

Raider and Warlord.

With regular attacks, Sohei's Seven-Force Strike insta-kill attack does 95 damage.
With feats, Hito's Senbonzakura insta-kill feat does 200 damage.

The highest natural health is 140 HP with Warlord, Shugoki, and Lawbringer.
With feats and perks, Black Prior has the highest potential health with 130 base health + 15% with Tough as Nails feat (19.5 HP) + 16 HP with Bulk Up perk to a total health of 166 HP.

7.5 m/s is the fastest sprint speed held by Peacekeeper, Shaman, Shinobi, Orochi, and Afeera.
Yet, Shinobi's Super Sprint makes him the fastest hero with 8.5 m/s which can be combined with the perk Supersonic that adds 15% movement speed in Revenge, adding ~1.3 m/s to a total speed of 9.8 m/s.
