Chance to Cast

Diablo II Notation Basic Class Skill Item Ally Quest Area Monster Tale All Skills Fire Skills Skill bonus Oskill Aura Equipped Charges Charged suffix Chance to Cast On Attack On Striking When Struck When You Die Kill an Enemy Level-up Chance to Cast gives a percentage chance to use a skill when triggered by an event and without costing any mana. Skill level cannot be increased, but equipping multiple Chances to Cast of the same skill, level and event will result in the individual percentages being added together to apply a single Chance to Cast of that skill, level and event (although >100% Chance to Cast is redundant). [1] Skills used receive passive bonuses including synergy bonuses, but they do not apply bonuses to other skills. The existence of pets summoned will be unstable unless player invests skill points in the native skill or acquires it from an oskill. Pets will not be summoned by mercenary. When equipping two weapons, Chance to Cast on Attack, on Striking and When You Kill an Enemy are restricted to the weapon on which they spawn (Chance to Cast on one weapon will not apply to the other). [2] No Chance to Cast of any kind is applied by Whirlwind. Skill level Chance to Cast normally specifies a set skill level (slvl), however on certain items the slvl depends on the generating source: it is calculated from the item level (ilvl) and the required level (rlvl) of the skill. [3] The table below specifies the ilvl required for a particular slvl, depending on the rlvl of the skill. Rlvl Slvl 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 1 1 5 9 13 17 21 25 29 33 37 41 45 49 53 57 61 65 69 73 77 6 1 10 14 18 22 26 30 34 38 42 46 50 54 58 62 66 70 74 78 82 12 1 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 18 1 22 26 30 34 38 42 46 50 54 58 62 66 70 74 78 82 86 90 94 24 1 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 30 1 34 38 42 46 50 54 58 62 66 70 74 78 82 86 90 94 98 This applies to the seven Unique items listed below. In practice, the lowest slvl available is determined by the level of the Unique item or the level of the base type, whichever is higher. The table specifies the minimum ilvl corresponding to a particular slvl. Given the ilvl (level of the source generating the item) the slvl is then fixed by ilvl and rlvl: Unique Item Level Skill Rlvl Slvl Chance Event 7 8 9 10 11 12 13 14 15 16 17 18 19 20 Lightsabre Phase Blade 73 Chain Lightning 18 70 74 78 82 86 90 94 5% Attack Hellslayer Decapitator 73 Fire Ball 12 72 76 80 84 88 10% Attack Stormrider Tabar 49 Charged Bolt 1 49 53 57 61 65 69 73 77 10% Striking The Rising Sun Amulet 73 Meteor 24 72 76 80 84 88 92 96 2% Struck Snowclash Battle Belt 49 Blizzard 24 48 52 56 60 64 68 72 76 80 84 88 92 96 5% Struck Boneslayer Blade Gothic Axe 50 Holy Bolt 6 50 54 58 62 66 70 74 78 82 50% Struck Stormspire Giant Thresher 85 Charged Bolt 1 77 2% Struck Casting order Casting order is normally irrelevant: if two or more skills are triggered by the same event, all are cast, even if there are two or more delays; those for each skill are not applied. [4] [5] However, an 11 frame delay is applied from the action frame. During this delay no active skills can be used, although Scrolls of Identify and Town Portal placed in the belt can be used. [6] [7] This 11 frame delay does not interrupt an attack sequence if Chance to Cast is applied during that sequence. The delay can be applied from the action frame of any individual attack in the sequence, so if it is applied by an attack early in the sequence then the delay may end before that sequence ends. If multiple attacks in a sequence apply Chance to Cast, the delay is applied from the last attack in the sequence to apply it. [8] Casting order only becomes relevant when two or more skills using Next Delay missiles are cast (since the next delay of the first cast may prevent those following from applying to the target), or when two or more curses are cast (since the last cast will normally overwrite those preceding it). The factors affecting casting order for all remaining cases take precedence in the order described below. Trigger event Event Curses [9] Other [10] Active On Striking On Attack When You Kill an Enemy When You Level-up On Attack On Striking When You Kill an Enemy When You Level-up Passive When Struck When You Die When Struck When You Die Equipping order When the trigger event is the same, equipping order determines casting order: curses are cast in the reverse order to which they were equipped (first equipped, last cast) [11], while skills are cast in equipping order (first equipped, first cast). [12] Only when the character swaps weapons, gains a level or recovers a corpse after dying will weapons or other items by equipped in the following order: [13] Equipping order Head Neck Torso Right arm Left arm Right ring Left ring Belt Feet Gloves Finally, any swap weapons (II) on the right then left arm will be equipped in Expansion games. After recovering a corpse, if item requirements cannot be met without +Strength (or +Dexterity) bonuses from items equipped later, then items normally equipped before will now be equipped after those later items; if an item cannot be equipped without its own Strength (or Dexterity) bonus, it (and any later item(s) which cannot be equipped without that bonus) will be placed in inventory or remain on the corpse if there isn't sufficient space. Displayed order When the trigger event and item are the same, casting order is determined by the displayed order: curses are cast in descending order (first displayed to last), [14] while other skills are cast in ascending order (last displayed to first). [15] The table lists curses and other skills in casting order, not displayed order: Curse Other Taunt Howl Lower Resist Decrepify Attract Life Tap Confuse Terror Iron Maiden Weaken Dim Vision Amplify Damage Hit Blinds Target Hit Causes Monster to Flee Frost Nova Nova Chain Lightning Teeth Poison Nova Twister Volcano Tornado Howl may be cast second, but due to its mechanics it is actually applied last. [16] Twister, Volcano and Tornado mechanics will often result in variations between casting and application order. Skill Level When the trigger event, item and skill are the same, casting order is determined by ascending order of skill level: the lowest is cast first and the highest is cast last.
