Spell Damage Increase
Spell Damage Increase (SDI) is an item property that increases the damage of most magical attacks that are cast. This property is capped at 25% in PVP provided you dont have more than 30% of a skill in two different spell lines or Animal Taming or Parry. Then, you will become "focused" to that spell line and can display it from your titles menu, under overhead name, skills. So, if you have Imbuing, mysticism and focus you can be a focused mystic, but not if you have mysticism and 31 in evaluating intelligence. It's noteworthy that chivalry is amongst the magical lines even though it has no spell affected by SDI. So, if you have 120 magery and 120 chivalry, you won't be a focused mage. If you are not eligible to be focused, then your SDI pvp cap will be 20%. For PvE there is no cap on spell damage, so pack it on.
There is no formula needed for Spell Damage Increase because it is a true conversion, a 10% increase means your spell damage is increased 10% and so on. The intensity range of the Spell Damage Increase item property is 1% to 18% for found rings and bracelets. The apparent maximum is 50% for special items (e.g., Shattered Obelisk Invasion Spellbook).
As with most code over time, Spell Damage Increase is not as straight-forward as it seems. It does affect Poison Strike and Wither, but it does not affect Pain Spike or Holy Light. It works with Word of Death, as the spell is not dependent on a secondary ability check, e.g. like Pain Spike, which involves Spirit Speak, or Holy Light, which involves Karma.
Calculating Spell Damage
- A character's skill level of evaluating intelligence is the first thing that comes into play in calculating the magery base spell damage. The formula for how much spell damage your getting from your Evaluating Intelligence is this: ((evaluating intelligence * 3) / 100) + 1.
- Similar with Spirit Speak for Necromancy Spells and Focus or Imbuing for Mysticism Spells, Arcane Focus for Spellweaving Spells.
- The next factor involved in spell damage is intelligence. The formula for this is 1% spell damage increase for every 10 points of intelligence, or (intelligence / 10) and drop the decimals.
- Spellweaving spells Arcane Empowerment and Reaper Form increase spell damage.
- A bards Inspire (giving SDI) & Invigorate (giving intelligence) buffs the spell damage and too.
- Berserk ability of the gargoyle race may increase SDI (up to 12%).
- Getting the Guild of Arcane Arts trade deal city buff increases the SDI value by 5%
- Inscription Skill bonus. This is a 10% increase in the base damage for Magery Spells. (This bonus only takes effect when a character has achieved the level of Grandmaster or higher in Inscription.)
- Being cursed by a target's Blood Oath.
- Factor in any SDI imparted from items.
- Don't forget the well timed usage of an Spell Focusing Sash.
- Last but not least, the Summer Dragonfish Pie gives a straight +5 spell damage.
