Terminology note: KS = Known Space, i.e. any null, low, or high-security system. JS = J-Space, i.e. any wormhole system.
To learn about a wormhole, right-click it and select Show Info. The top two sentences are irrelevant.
The third sentence (beginning, “This wormhole seems to lead…") narrows down the hole's destination:
- Plain "unknown" space is class 1-3 JS, “dangerous unknown" is C4-5, and “deadly unknown" is C6.
- High/Low/Null Security is that class of KS, "Triglavian" is Pochven and Thera is, you guessed it: Thera.
- If you're currently in KS you can further differentiate C1 from C2/3; if the last sentence says "up to medium ships" will fit, it's a C1.
- To suss C2 from C3 and C4 from C5 you must either yump in and look up the J-number or learn to discern holes visually.
The fourth sentence indicates a hole's remaining life:
- "This wormhole has not yet begun its natural cycle..." = max life ("fresh").
- "This wormhole is beginning to decay..." = between four hours and max life (also "fresh").
- "This wormhole is reaching the end of its natural lifetime." = 0-4 hours ("EOL" i.e. "end-of-life", “critical" in Tripwire).
The fifth indicates its remaining mass:
- "This wormhole has not yet had its stability reduced..." = over 50% of mass remaining ("stable" or "healthy").
- "This wormhole has had its stability reduced..." = 10-50% of mass remaining (“destab", "shrunk" or “first shrink").
- "This wormhole has had its stability critically disrupted..." = under 10% of mass remaining ("crit").
The last sentence indicates what size class the hole is, i.e. which types of ships will fit through.
- "Only the smallest..." = S: destroyers, ZMPE'd HICs and smaller (these are often called “frigholes", somewhat confusingly).
- "Up to medium..." = M: battlecruisers, industrials, Nestors with no onlined plates and smaller (no other battleships).
- "Larger ships..." = L: all other battleships, Orcas, and smaller (one type of L—Pochven's C729 reverse-static—can also fit Bowheads).
- "Very large..." = VL: all ships up to and including freighters/JFs/Rorqs or all ships up to and including carrier/dread/FAX (the latter subgroup includes the former).
WARNING: NOT ALL HOLES OF A PARTICULAR SIZE CLASS WILL ALLOW THE SAME NUMBER OF SHIPS THROUGH.
That is to say: only S holes all have the same total mass limit. M, L and VL vary within their own classes.
For example, D845—an L—will pass 5 million tonnes, whereas Unidentified Wormholes—also Ls—only pass 750,000 tonnes.
The jump range of wormholes is 5 km (double that of stargates/Ansiblexes).
To see how much mass a particular hole has, you must identify its type, which is the non-K162 side. Then you can Control + F
on this page.
You can also use the above link to check whether a VL is freighter-and-smaller or caps-and-smaller (but don't be dumb with either).
All frigholes are now effectively unrollable. They were rollable for years due to a bug and many evictors and risk-averse krabs cried like stuck pigs when they were fixed.
I think it's great that they're unrollable. The risk should be factored into eviction planning and krabs should
HTFU. YMMV. May Bob bless and keep you.
Unidentified or "Uni" or "Drifter" wormholes have different mechanics to normal holes and are only used for certain purposes. A Uni TLDR:
- Both the KS and JS sides of Uni-to-KS connections have deadspaced warpins 89 km from their holes.
- You can land on these holes at zero if you're lucky or have prep time.
- These holes can be rolled like normal holes (with additional risks).
- The KS sides:
- have entrances which spawn only in systems with Jove Observatories;
- if present, show on the overview as a beacon called Unidentified Wormhole (with no corresponding scannable signature);
- lead to one of five JS systems colloquially named after unique combat sites inside them which are indicated by the first letter of the entrance wormhole:
- B735 = Barbican = J110145,
- C414 = Conflux = J200727,
- R259 = Redoubt = J174618,
- S877 = Sentinel = J055520,
- V928 = Vidette = J164710;
- and are randomly patrolled by these three classes of NPCs, none of which can be easily handled if unprepared:
- Drifters—i.e. [Name] Tyrannos—which have very high tank and DPS and a doomsday that can insta-zap subs (and dumb caps),
- Diamond rats—only in the regions where they naturally spawn—which will shred unwitting fleets, and
- Autosythian Lancers, which can be tanked en route to a hole w/logi but which can easily pop unsupported subs.
- The JS sides have no convenient wormhole beacons. Instead, there are many scannable signatures, all of which are wormholes.
- The majority are KS-bound deadspaced holes, but there's always at least one connection to other JS; such holes aren't deadspaced.
- The holes have, on average, 750,000 tonnes worth of transit capacity and fit BS/Orcas and smaller.
