As with Levelled skills such as Martial Arts, can a an Iguana with ED: Level 2. Ejection System downgrade this and use ED: Escape System?
This is incorrect, equipment is leveled just like skills. That’s why msv3 includes the benefits of msv2, same with holoprojector. So there is no reason you can’t downgrade your ED2 to ED1 when it is advantageous. I’ll admit it feels weird from a fluff perspective, but not too weird that I wouldn’t let someone do it.
So is all levels of Metachemistry and, crucially, Infiltration Level 0 but not Infiltration Level 1+, so by the logic that it's Obligatory you can never use any level of Infiltration other than Inferior.
There is no ED: Level 1. It is simply ED: Escape System. Which isn't levelled with ED: Level 2. Ejection System.
I think that's stretching the logic a bit. The Level 1 is implicit in a very obvious way due to having the same base nomenclature. It's like saying Full-Auto L2 doesn't also include the bonus to Burst because the skill doesn't have the word "Level" in it. Curiously, however, Akbar Doctor isn't Doctor L3, btw, but explicitly grants Akbar Doctor. Neither Akbar nor Doctor+ can roll a regular Doctor roll with no extra bonuses (it's a curiosity that they didn't make it levelled, but it has no real practical impact).
You may want to take a gander at this page: http://infinitythewiki.com/en/Equipment Also, consider that Holoprojector Level 2 does not have any text which grants the user Holoprojector Level 1, and the Holoecho state does not explicitly give the user permission to use Holoprojector Level 1 if they don't have it (only gives permission to combine the two). However, we clearly have examples which contradicts your position (bold and underline below): Holoecho state Game Example: In their Reactive Turn, the Fusiliers Angus and Silva see how three Lù Duān come at them. In fact, there is just one Lù Duān with its Holoprojector L2 activated. Trusting in its equipment, the Lù Duān declares Move to get closer to its enemies. Angus and Silva decide to delay their ARO until the Remote declares the second Short Skill of its Order. The Lù Duān declares Surprise Shot L1, revealing itself automatically. The player removes the holographic decoys and places the model in the position he has already noted. Now Angus and Silva declare their AROs, BS Attack, but they have to apply the -3 MOD to BS provided by Surprise Shot L1. If the Lù Duān survives this shooting and finds a place outside enemy LoF, it can reactivate the Holoecho state. However, it can even combine the effects of Holoprojector L1 with its Holoechoes to confuse the enemy. Spending an Entire Order, the player replaces the Lù Duān model with a Yáopú Pangguling, a Remote possessing the same Silhouette value, and places the other two Holoechoes in base to base contact with the Pangguling, taking note of which one is the real trooper. However, let's suppose the Lù Duān had not activated the Holoecho state. Then, at the beginning of its Reactive Turn, during the Tactical Phase of its opponent, the Holoecho state will activate automatically, if the Remote were outside LoF of all its enemies.P
Find the differences Equipment: Levels Like Special Skills, certain pieces of Equipment are divided into several alphabetic or numeric Levels that represent grades of effectiveness and refinement of the same basic technology. Special Skill Levels Some Special Skills are divided into Levels of expertise with distinct effects and uses. Unless otherwise stated, any numerical Level of a Special Skill automatically grants all lower Levels of the same Skill. For example, a Level 3 also grants Levels 1 and 2. Conversely, alphabetical Levels such as Level X state whether they grant any other Levels of the Skill or not.
Full Auto Level 1 is a levelled skill. That's why it works. I honestly can't think of a Levelled Skill they doesn't explicitly have, you know, a Level associated with it.
I'm shocked, shocked I tell you to discover that there are inconsistencies in the wording of rules! Never has this happened in the history of gaming, call the police! Actually, it does, but it's buried in the Holoecho state rules, so it's understandable that you missed it.
No it doesn't. I know the line you mean, but it doesn't say you get access to the skill, it says you can combine them. There's a huge difference. Not to mention that as a skill you would have to enter Holoecho state before you gained access to Holo1 which isn't what happens in the example with the Lu Duan In either case, it doesn't need to tell you you get access to the skill, because there is a rule that says you treat levelled equipment similar to levelled skills. And so is Escape Device Level 2. Your argument is that the level 1 version doesn't have "Level" in its name. That's a fairly weak argument when the second level has just that.
Then you need to explain why fairly simple logic and pattern matchin as well as game examples don't agree with you.
Try to find a GENERAL RULE that states it. There is not. It is only included in the Leveled Skills paragraph. Every single equipment has its own rule that DOES NOT include the previous level. It states "works as previous level with these mods" to avoid repetition of wall of texts. The only case where it is cloudy, is Holoprojectos. But in this case it is clearly stated how it works within examples (that is the premium error of N3 rules - including rules in the examples - but this is another can of worms)
@Mahtamori my argument is that there is no ED: Level 1 not that ED: Level 1 is not levelled with ED: Level 2. Point me to the equipment ED: Level 1 in the rules. You can't, because ED: Level 1 does not exist. Regardless of whether you can use the lower level of levelled Equipment, to be levelled it requires an alphabetical or numeric level: ED: Escape System does not and therefore is not. Now you can argue about whether ED: Escape System is the mistake or whether ED: Level 2 Ejection System is the mistake, but at the moment the rules do not include the text required for them to be levelled with each other.
FYI the wiki quote is not an exact copy pasted from the rulebook which includes a reference to the skills level page, making it pretty clear that equipment is leveled just like skills. Also see msv3 which does not state that it includes msv2, but no one has ever said that it doesn’t. ED2 was added in HSN3, so that would appear to be the reason that ED1 is not written with a level. It’s pretty obviously an editing error which are common in this game and no one usually bats an eye at (see Full Auto and Meta Chemistry). Also I believe this would be the only case of a level 2 without a level 1 to exist in the rules, so pretty clear they meant it to be level 1.
