Hello!
I have a couple of Questions and Suggestions as well.
Lets start with my Questions/Doubts
1.- Shiny Charm. It's just a small doubt I have: Do you have to defeat the wild Pokemon with the Pokemon holding this item? Or is it only necessary for the Pokemon holding the charm to deal some damage and then the effect is "somehow" automatically activated?
2.- Jewels/Gems. Is the increased move a random move? or is it possible to choose which move we would like to boost? (btw, good thing that you increased damage to 20%).
Next is a doubt AND a suggestion:
3.- Genius Wing. This is more of an arithmetic doubt. Description is as follows: When HP drops below 20%, its resistance raises by 50% but damage is being reduced by 30%. Can be used only by flying type Pokemon... this means that Flying types' weaknesses then become 1.5x instead of 2x? or 1x instead of 2x?.
I would like to know exactly, because if resistance is 1.5x, then I would like to suggest an increase to 25% or even maybe 30%, like usually damage-buffing abilities do (overgrow, torrent, blaze...)
Why? Let's analyse the following example:
A Cloned Pidgeot has 22k total hp, which means that 4.4k hp is 20%. If Pidgeot is hit by a Rock/Ice/Electric move with 3k based-damage (6k total 2x damage) while holding this item, it would still faint... because the move would deal 4.5k hp (even more, when the pokemon is a Shiny/Cloned Version).
I know that Pidgeot is meant to be defeated by a Rock/Ice/Electric type Pokemon. However, the purpose of held items is to help our Pokemon do better and have a better performance in duel and PvE. Just as I suggested, with that small boost of 5 to 10%, our Flying Pokemon (Emolga (22.7k hp), Skarmory (21.5k hp), Staraptor(21.5k) etc...) would still loose against their weaknesses, but that would give them at least time to use 1 move and deal something of damage.
IF resistance would be 1x, instead of 1.5x, then please ignore everything I wrote and leave it like that
4.- Terrain Extender. I like that it increases terrain moves' damage in 10%. However, I feel like we already have a lot of this effect already in game. There are some Pokemon with Technician ability, there is also this other held item, Power Lens, which boosts damage of TM in 15%.
I know Terrain Extender benefits pokemon which have a Terrain move already in their moveset, but I think this held item could do a bit better. This is why I would like to suggest making the area of terrain moves bigger, meaning to say adding 1 sqm (maybe 2 if it's not too much?) around it. I feel this would be really nice in both, duel and PvE. The 10% boost should stay like that, but the area of damage should definitely be increased.
Bulbapedia says: If the Pokémon holding this item creates terrain with its own move (Electric Terrain, Psychic Terrain, Grassy Terrain, and Misty Terrain) or Ability (Electric Surge, Psychic Surge, Grassy Surge, and Misty Surge), that terrain lasts eight turns instead of five turns.
I feel like saying "Terrain moves should hit 1 or 2 more times" could make the terrain moves a bit too op (damage-wise). But leaving the normal damage + a bigger area sounds more viable and sane.
5.- Rocky Helmet. This is my last suggestion: change effect from "always reflecting 5% damage" to "Reflecting 5% damage from moves of direct contact" or maybe you could increase to 7%?. Bulbapedia says: It is an in-battle effect item that damages the attacker if the holder is hit by a contact move.. I guess maybe you wanted to do something different from Bulbapedia, but I feel like ALWAYS reflecting 5% damage could lead to a huge disadvantage in duel. Plus, it kinda doesn't make sense that if my Pokemon uses Hydropump, it would get 5% of reflected damage from a helmet that it didn't even touch!
What do you guys think about my suggestions?
Thanks in advance for reading!
