So I don’t think we need to focus on exact same spell shared between specs or even similar spells like Mind Blast and Holy Fire as yes they both have a cast time, a cooldown and deal damage so it is a good spell to use as a merged new spell similar to FrostFire Bolt replacing Frost Bolt and fire Ball. But the thing to keep in mind is that Holy is a healer and Shadow is a DPS. Meaning having Holy Fire being a central core spell for Archon to revolve around is not going to satisfy most Holy players as it just becomes another form of Discipline in dealing damage to heal instead of healing outright.
Having said that…
I just repost my ideas for how yo manage/merge Holy and Shadow spells for Archon that I posted in the Oracle thread already.
I have really 2 versions of ideas. They are mainly just raw ideas and are not to be thought of as a complete tree but instead as a concept / possible direction Archon can go in.
Version #1
Holy/Shadow (Archon)
- Psionic Storm (Archon Keystone)
[Replaces Holy Word: Sanctify] (Holy)
[Replaces Shadow Crash] (Shadow)
Create a Psionic Storm at the targeted location for 10 seconds. While in a storm, enemies take damage every 0.5 seconds, increasing by 20% for each consecutive instance of damage, up to 400%. - Psionic Link
Your single target spells damage and healing is replicated to every target within Psionic Storm. - Psionic Surge (Archon Capstone)
Targets within your Psionic Storm take 10% increased damage and healing from your spells every second, up to 100% - Psionic Energy
- Holy: Healing done from your Holy Word spells generate a stack of Psionic Energy. Reaching 20 stacks fill you with power and causing you to erupt, dealing pulse healing to your allies within 20 yards every second for 3 seconds.
- Shadow: Damage dealt by your Shadow Word spells generate a stack of Psionic Energy. Reaching 20 stacks causes the next target to receive damage from your Mind Spells to erupt, dealing pulsing damage to every enemy within 20 yards every second for 3 seconds.
- Psionic Power
When Psionic Energy erupts, your Psychic Link damage and healing increases by 5% for 30 seconds. Stacking up to 3. - Psionic Force
Psionic Energy pulse deals 100% more damage and healing with each consecutive pulse.
Holy (Archon)
- Psychic Link
Your single target Holy Word spells heal 25% of the healing done to targets affected by your Renew within 40 yards. - Psionic Focus
Gaining a stack of Psionic Power increases the healing of your single target healing spells and reduces the mana cost by 10% per stack.
Version #2
Archon
Dot/Hot
- Psionic Word: Disintegrate
[Holy: Replaces Renew][Shadow: Replaces Shadow Word: Pain]
A word of pure energy that heals your ally or damages your enemy over 15 sec.
Your Psionic Blast causes each target affected by Psionic Word: Disintegrate to burst the healing and damage done to every target within 5 yrds.
Direct damage/healing
- Psionic Blast
[Holy: Replaces Holy Fire][Shadow: Replaces Mind Blast]
Blasts the target with Psionic Energy that heals your ally or damages your enemy and causing additional healing and damage to the target for 50% of the remaining amount of Psionic Word: Disintegrate. - Psionic Word: Onslaught
