Similiarly to the already posted Tenfell

Gallows: Unrest doesn't effect production.

Correct is: Gallows: Unrest doesn't affect production.
In: data/english/core improvements/CoreImprovements.xml

There may more occurences of effect/affect.

Also please change the thread title to "grammar and spelling", I almost didn't look because spelling and grammar are  not the same thing.

My OCD senses are tingling, because I am posting in here with a spelling mistake.

In the scenario map trigger data file when you enter the Procipinee hoarder cave the answer text says: "If I enter the cave, I will be carefully careful"

Legacy of Serrane: tooltip has the old description.

Unlocks bazaar improvement (still true) and the warhorse, which boosts the rider's attack (should be: boosts rider's attack and initiative for the first turn).

Caravans are immune to attack (All caravans seem to be immune now?)

Mancers:

Their tooltip should state that the faction has the road-building trait (which is, incidentally completely OP as I mentioned in another thread).

Caravans are not currently immune from attack.  I had 3 of them destroyed by monsters in my last (1.0) game.

The Scroll of Fortune says "This ancient scroll gives the reader the ability to discover money where its least expected."  It should be "where it is least expected" or "where it's least expected".  "it is" would be clearer.

From LH Scenario,

occur is a message from Queen Procipine about Iru T' Alavar.

Part of the message reads: "You would to well to rest..."

Should read: "You would do well to rest..."

The Ghost Helm quest says "There are no tomb's here ..." It should be "tombs", not "tomb's".

 Intro to Ascian Quest:  Lady Umber would call for "aid"  (help) not an aide (servant).

Grammatically ok, but Letter of Mark could be a Letter of Marque... (a little more old-timey).

Edit:  And when Procipinee meets me and says reclaiming the land is a blessed gift, she should make reference to my sov's name, not the Kingdom as a whole ( just change the the tag in the xml).

Thanks!

In the scenario, at the Forge of the Overlord, there's this:

"When you stand on it you feel the complete power of Elemental running through you.  You feel Procipinee straining to keep the way into the forge open an through that whole into the world ..."

It should be hole, not whole.

The great revival...

Tooltip for Spell Mastery currently says "Percentage chance this units resistable spells..."
Change "units" to "unit's".

Tooltip for Research currently says "The more research your produce per season..."
Change "your" to "you".

When you cast Haste on a unit it says Hasted. Shouldn't that be Hastened?
