1) Something acquired in battle is not the same as something acquired only in battle.
2) In "Lord of the Land," I added two spells that were missing. But from your comment, it's unclear whether it gives a bonus, doesn't give a bonus, or gives a bonus but not the right one. So, I'll leave it as is – 4 spells in the description.
3) Regarding creature skills. You can, of course, post them, but there needs to be more than just one Thunderlord. There's also Berserk from the dwarves; its skill name isn't translated. Maybe there are others. We'll gather them over time, and I'll add them.
2) Hmm. Let me try again – "Lord of the Land" DOES NOT give any bonus for "Earthquake." NONE AT ALL. In the original/VS, it only gives +4 to spell power for "Fire Trap." In PoD, it also gives a bonus for "Crystal Prison" and "Wall of Blades." That's it.
The rest was about my research into this problem. I mean, anyone who has ever leveled up the Summoning magic has definitely wondered what "+4 to spell power for Earthquake" even means if this spell doesn't use spell power and has fixed damage that depends only on Summoning magic. It's like "+20 to mana of lamellar armor." It's nonsense. At first, I thought that "Earthquake" used to have damage scaling from spell power, and "Lord of the Land" worked for it just like any other similar skill. Then, the scaling was removed, and the meaningless bonus that now does nothing remained. But it turns out that's not the case; there's no bonus at all.
3) Exactly, Berserk! I remembered that someone had an untranslated ability, but I couldn't remember who. Thanks.
I'm posting what I have; if anyone else remembers any errors in the descriptions of creature abilities, I'll be happy to fix them.
For now, I've fixed "summoning a storm" ("those inside the cloud" replaced with "those creating the cloud"), "berserker's rage" (now in Russian), and simply because it caught my eye, "cleansing" (missing period at the end of the description) and "lash attack" (extra space before the period at the end).
P.S. If anyone other than me is interested, I checked that in the original/VS, "Devil Strike" did indeed have a 40% chance to trigger. In PoD, the chance was reduced to 30%, and the description, as usual, was left unchanged.
