[SPOILER="Spoiler"]If it was me... I would add "customizations" to Spirit Weapons. What do you mean? Well, Spirit Weapons should be unique and tailored to each individual's will. To add some customization ideas I would do the following:
Each Spirit Weapons start off with "1" -slot- of customization. You can add more slots by combining it with an Artisan Chisel (they can be obtained in-game from drops from field bosses as well as a 100% success one from the NX shop, failure to "chisel" a slot will result in -1 durability loss. However if you have repair protection potion, it will take that instead).
Spirit One-handed Weapons (Swords, maces, etc.) will have up to a maximum of 3 slots
Spirit Wands(ice wand, fire wand, etc.) and Bows (LLB, HLB, etc.) will have a maximum of 4 slots.
Spirit Two-handed Weapons (Claymore, Two-handed Sword, Dragon Fangs, etc.) will have a maximum of 5 slots.
To add in a special ability, you first need to either make a Spirit Stone or have it drop from monsters and there's different levels to it, but each stone can be slotted into a Spirit Weapon for each customization. However, you can only at best add the same type of stones two times to a weapon, no more, no less. Here are some stone examples:
*Unbreakable Will: -10% Critical Chance for the enemy
*Iron Wall: +40% Defense and +3% protection
*Sharp: +8% Critical Chance on Range, Melee Weapons
*Magic Vibration: +8% Critical Chance on Magical Skills
*Untimely Instinct: +5% Physical Critical Damage Increase, +3% Physical Critical Chance
*Studious: +5% Magical Critical Damage Increase, +3% Magical Critical Rate.
*Unannounced Rage: +8% Physical Critical Damage (does not apply to any non melee skills, aka gold strike, spear of god, etc.)
*Unbelievable Transcendence: +8% Magical Critical Damage (does not apply to any non magical skills, aka gold strike etc.)
*Chanting: -20% Casting Time
*Saintly Love: +30% Healing Recovery, +15% Party Healing Recovery, -20% Healing and Party Healing MP Cost
*Determination: Start out with an additional +10% aim speed when loading any Range Skill.
*Efficiency: -15% MP Cost
*Splintered Fate: +1 additional Crash Shot Target.
*Understanding: Chain Cylinder Rate +5%, -20% stamina cost on alchemy skills
*Burning Veil: +5% chance to poison the target, target loses hp over time.
*Silence: +10% chance when attacking to silence your target, unable to use any skills concerning MP for 10 seconds.
*Heaven on Earth: +5% chance to activate when being attack, immune to all damage for 7 seconds.
*Shattering Hole: +5% chance to activate when attacking attack, target's defense -20, target's protection -5%
*Adrenaline Fierce: +5% chance to activate when being attacked. Unable to be stunned/knockback/knock down for 6 seconds, however damage taken is unaltered.
etc.
*Vine Hold: +5% chance to activate when being attacked. Target is unable to move for 7 seconds.
*Lady Killer: +5% chance to activate. When fighting a female enemy, additional +10% (applies to magic too) base damage is added.
*Shadow Killer: +5% chance to activate when fighting any monster with Shadow/Corrupt in their name, additional +30 base damage.
*Beast Slayer: +5% chance to activate when attacking beast type: additional +10% base damage is added.
*Zombie Killer: +5% chance to activate when attacking any undead: +10% base damage is added.
etc.
*Shock Wave: +5% chance to activate when attacking. AOE Radius +200 to any AOE skills.
*Vampiric: +30% chance to convert 10% of damage dealt to enemy into HP (however cannot cure injury) - Unique, can only equip one of them.
*Mana Stealer: +30% chance to convert 10% of magic damage dealt to enemy into MP - Unique, can only equip one of them
*Cruel Eyes: +5% to activate when attacking, Physical and Critical Chance +100%
Of course there's different levels of strength of stone, with each level giving slightly more stats. Remember at most, you can only add 2 of the same stones on a weapon.
normal(requires 1 social) - > average (requires 21 social) - > fine (requires 30 social) - > finest (requires 40 social) - > legendary (requires 46 social)
This will make ego weapons more customizable and when fully upgraded, more appealing than regular weapons.
A Spirit 2-h will look like this:
Slot 1: Unannounced Rage
Slot 2: Unannounced Rage:
Slot 3: Heaven on Earth
Slot 4: Adrenaline Fierce
Slot 5: Zombie Killer
or Spirit Wand:
Slot 1: Studious
Slot 2: Saintly Love
Slot 3: Chanting
Slot 4: Unbelievable Transcendence
or a Spirit Bow:
Slot 1: Unannounced Rage
Slot 2: Vine Hold
Slot 3: Vampiric
Slot 4: Cruel Eyes
*When you have 2 of the same category stones... such as Unannounced Rage and Sharp or 2x Sharp or 2x Unannounced Rage, your Spirit Weapon's glow will change... such as the mention combo will give it a burning aura. Or having 2 Saint Heal will give off a Yellow glowing light, etc.
Each Spirit Weapon will have their own customization tailored to each user's unique taste. Hopefully it will seem more appealing for people to use their Spirit Weapons more and gives a unique advantage over upgradable weapons.[/SPOILER]
Just looking at that list, I'd probably spam the living hell out of Chanting, and swap to a Phoenix Fire Wand ego.
-80% cast time fireball plz
Kidding, of course. Although, I'm slightly surprised there's nothing that would cause attacks to inflict poison.
