Single Class Skill Lines
• Bard (tonal architecture, support, or classic minstrel
• Artificer (summon constructs to help you, throw down Dwemer electrical traps, etc)
• Monk (Hand-to-hand combat is used by a ton of NPCs already. The weapon displacement could easily be overcome by adding an effect when the skill line is being used)
• True Warrior or Barbarian (no combat with no magic abilities)
• Daedric Cultist (so many possibilities, but imagine a Sheogorath skill line that randomly applies major buffs or debuffs when skills are used. You cast a spell, butterflies go everywhere, and things either get much easier or much more perilous. Hey, maybe the spell has a low chance of turning your target into a goat too)
• One-weapon and rune/spell/crossbow (Dawnguard style)
• Druid (focused on shape shifting)
• New Lycanthropy options (even just as visuals and minor changes to existing skills, ie. Instead of the leap, a wereboar could charge for a headbutt)
Additionally, can we now get skill Styles that just add mundane appearances to skills? Help those templates out by making their spear look like a regular, non-aedric spear.
