Is this reflavouring of the Dao Genie warlock patron balances?

I am intending on reflavouring the Genie, so that each type of Genie patron is instead a Fey Court themed around the seasons. All but one of the Genies work without changing.

Here is how I’m intending on reflavouring each variety:

Marid, winter; Efreeti, Summer; Djinni, Autumn; Dao, Spring.

However Dao is themed around stone, so I intended to change the extra spells to these for levels 3-5.

  • 3rd: Haste
  • 4th: Grasping Vine
  • 5th: Wrath of Nature

These weren’t my only considerations, but I think they might be the best ones to pick.

My concern was that Haste might be too powerful however I thought Plant Growth, Daylight, and Aura of Vitality would be underpowered.

Are the new spells balanced in relation to what they were previously and the other genie options?

Can a Fathomless Warlock move their Tentacle of the Deeps without attacking?

In Tasha’s Cauldron of Everything, a warlock with the Fathomless patron can summon a Tentacle of the Deeps, whose description includes the line

As a bonus action on your turn, you can move the tentacle up to 30 feet and repeat the attack.

"Can…and" seems to suggest that you must do both: move and attack. "Up to 30 feet" means you could move it 0 feet and repeat the attack, but can you move the tentacle without attacking?

What spells with material costs or permanent effects could the Warlock: The Genie’s Limited Wish ability apply to?

I’m looking for ways to take the most advantage of this new ability from the upcoming Tasha’s Cauldron of Everything:

You entreat your patron to grant you a small wish. As an action, you can speak your desire to your Genie’s Vessel, requesting the effect of one spell that is 6th level or lower and has a casting time of 1 action. The spell can be from any class’s spell list, and you don’t need to meet the requirements in that spell, including costly components; the spell simply takes effect as part of this action. Once you use this feature, you can’t use it again until you finish 1d4 long rests.

Most of the spells with material costs or permanent/"until dispelled" effects I’ve come across either have a cast time longer than 1 action, or are level 7 or higher. So far the only spells I’ve found are Revivify and Continual Flame. What else am I missing?

Can a Pact of the Chain Warlock summon their familiar in an invisible state?

As a Pact of the Chain Warlock, you:

…learn the find familiar spell and can cast it as a ritual. The spell doesn’t count against your number of spells known.

When you cast the spell, you can choose one of the normal forms for your familiar or one of the following special forms: imp, pseudodragon, quasit, or sprite.

The imp, quasit, and sprite all have the power to turn invisible.

Is it possible that when the Warlock calls forth their familiar, that the familiar starts in an invisible state? Or would they have to appear visible, and then immediately take an Action to turn invisible?

What is the earliest level a warlock can take Hellfire Warlock prestige class?

Hellfire Warlock Requirement is:

enter image description here

If I meet these requirements at level 6, can I go into HF warlock prestige class in level 7? I am currently a level 6 warlock however I have 9 skill points invested in Knowledge (the planes) and + 3 is coming from int modifier. Would that make Knowledge(the planes), level 12, or am I capped to level 9 (level + 3 SP) according to PHB?

PHB +3 SP rule:

If you want to pick up a new skill for your character, you can spend skill points equal to his or her character level +3. These skill points buy 1 rank each if the new skill is a class skill or 1/2 rank each if it’s a cross-class skill

What is the meaning of invoker level for a Warlock?

Hellfire Warlock prestige class (Fiendish Codex II: Tyrants of the Nine Hells variant, p. 89) mentions:

Invoking: At each level, you gain new invocations known, increased damage with eldritch blast, and an increase in invoker level as if you had also gained a level in the warlock class. You do not, however, gain any other benefit a character of that class would have gained.

What does the book mean by invoker level? The term invoker level is not mentioned in Complete Arcane under Warlock class.

Why would I choose anything other than a Greataxe as my Warlock Pact weapon?

In the PHB p.107 on Pact of the Blade boon it is stated:

You can choose the form that this melee weapon takes each time you create it (see chapter 5 for weapon options). You are proficient with it while you wield it.

Why would I ever choose a “low” damage weapon, compared to a Greataxe (for example) with its 1d12 damage? I’ll be proficient with whatever weapon I choose, anyway.

Can a warlock with Repelling Blast use Eldritch Blast to push 10 feet a creature of any size?

From the RAW ruling, unless I am missing official errata or clarifications documents from WotC I do not see any size limitations to the use of the Repelling Blast power of Eldritch Blast.

So it means you could push back up to 10 feet a creature of any sizes regardless of any context, weight, mass or your own size ?
