New mechanic/route
Repair route: a fleet searches for materials in the oceans to conduct repairs. When fleet is fully repaired, brings random materials found into assigned warehouse.
New Mechanic (or trait.)
Self Repair Trait: ship consumes materials in cargo hold at the top of every hour to conduct repairs on itself.
Self repair mechanic: any ships/fleets, when assigned, conduct repairs on themselves each hour (based on damages) with ship building materials in cargo bay. Ships defend 15% worse while under the repair mechanic if plundered or skirmished
Below applies to both ideas:
Wood repairs the fastest but least amount of health per unit
Cotton is the 2nd fastest, providing moderate healing.
Iron repairs slower per unit, but heals the most per unit
Food overall speeds up the repair process from Royal auxiliary effects. Extra 2% of ship repaired per unit with Food being consumed for repair mechanic.
Just brainstormed ideas. Thoughts?
