Mob statuses in hit damage; Energy Orb hops

[neeerp]

The v83 client reads a mob's statuses on every hit; HeavenClient ignored them. It now applies them to both magic and weapon damage. Energy Orb's ball also hops from mob to mob.

What changed

• Energy Orb (FUN_0094289f): the ball flies from 25 px in front of the shot's origin to the middle of its first mob, then on to each next one, 1.25 ms per pixel. Each mob is hit when the ball arrives, for the player's own shots and other users'.
• Magic damage (MDamage, FUN_00791617):
  • Disable turns the hit away, and Magic Immunity lets only a 0-in-100 roll through (otherwise 1);
  • the EVA and MDR statuses add to avoid and magic defense, and Magic Guard Up leaves n% after the defense;
  • Hard Skin stops every non-critical hit, and Weakness adds n%;
  • the hit scales by the weapon's percent for the spell's element (FUN_005d284f): the Elemental Wands and Staffs carry elemDefault and incRMAI/F/L/S/H.
• Weapon damage (PDamage, FUN_0078df87):
  • Disable makes the blow miss, and Physical Immune caps it at 1;
  • the EVA and PDR statuses add to avoid and weapon defense, and Power Guard Up scales it after the crit (not for Sacrifice);
  • Hard Skin stops non-critical hits, and fixed damage still skips all of these.

Not covered

• HeavenClient's base physical formula is still Journey's, not PDamage's.
• The respect chance against immunities.

Verification

• magic_damage and shot_path client tests extended.
