| A set of dormant, magnetic earth elementals in the form of tiny, very heavy pebbles. When released, the elementals are drawn magnetically to the center of nearby monsters, where they literally explode with rage at their rest being disturbed. Tremorstones usually land slightly off-target, and the user is always at risk of being hit. However, armour is extremely effective at repelling the lightweight fragments of rock from a tremorstone's explosion, so a well-armoured wielder has little to fear. Evocations skill increases the number of the elementals' explosions. |
A tin of tremorstones is an evocable item that generates several explosions of shrapnel. These are aimed in the general direction of nearby enemies, but there is always a risk of getting caught in the explosions yourself. The explosions are greatly reduced by AC.
This item is mutually exclusive with the condenser vane. Like with other miscellaneous evocables, only 1 tin of tremorstones (or condenser vane) will spawn in a given game.
Contents
Useful Info
Each charge of a tin of tremorstones will create 1 + 2 * log2(1 + Evocations/6) explosions[1][2] - at 27 Evocations, you'll get 5-6 explosions. Explosions are 5x5, and each explosion deals 6d6 damage, independent of your Evocations skill.[3] Explosions are reduced thrice by AC rather than once, and multiple explosions check AC multiple times. They have a to-hit of 40.
Each explosion will find the cell that is 1. within 3 tiles from you and 2. is in the "center of mass" of monsters. The explosion will be centered 1 tile away from that cell, meaning the tin can fire 2-4 tiles away from you. If there are no visible targets, then the explosion will explode at a random tile. Since explosions are 5x5, a tin is unable to hit a monster that's 7 or more tiles away.
A tin of tremorstones holds up to two charges, which are gradually replenished as you gain experience.
| Min. explosions | Evocations |
|---|---|
| 1 | 0 |
| 2 | 2.5 |
| 3 | 6 |
| 4 | 11 |
| 5 | 18 |
| 6 | N/A* |
*At 27 skill, you only have a ~91.9% chance for a 6th explosion.
Strategy
- A good item for crowd control. Heavily armoured players won't have to worry much about self damage, though this item will do little against enemies with high AC. Good targets include:
- High EV, low AC monsters, since the explosions have high (but not perfect) accuracy. Examples include spiders, deep elves, and
- Frail, but annoying monsters. At moderate Evocations (6-12 levels), 1 charge is likely to take out boggarts, moths of wrath, and floating eyes, etc.
- Take advantage of the targeting. Explosions are always 5x5, centered within 2-4 tiles from you, and target the biggest crowd of enemies. So if 1. the enemy is within 2-4 tiles and 2. inside a big group of monsters, you are almost certain to hit.
- Note that, if there are 2 or more groups of monsters in line of sight, the tremorstones might not hit anything.)
- A scroll of immolation combos well. Immolation creates flame clouds, increasing your damage output. And the resulting explosions will definitely hurt. As usual, don't let the explosions kill you.
History
- Prior to 0.30, tins of tremorstones did not alternate with the condenser vane. Also, if there were no visible tiles within 3 spaces of you (e.g. after reading a scroll of fog), the item would fail and waste a charge.
- Prior to 0.26, tins of tremorstones came with three charges instead of two.
- Tins of tremorstones were introduced in 0.25. They were introduced to replace the cone-targeted wand of scattershot.
