Appropriate database schema for heroes’ skills in a Tower Defense game?

In a Tower Defense game, each hero (or character) has some skills. Each skill has some "chance of appearance" (CoA for short) when attacking enemies and if appeared it has some "hit accuracy" (i.e. hit on enemies) (HA for short) and has effects on the enemies (if hit by the skill) (EoH for short).

Examples:

Skill #1: Frost 1, CoA: 50%, HA: 100%, EoH: (1) slow enemy down for 4s and (2) yield 200 damage points.

Skill #2: Frost 2, CoA: 100%, HA: 50%, EoH: (1) make enemy frozen for 8s.

I first tried to breakdown skills into "atomic" effects and come up with tables as below:

enter image description here

All looks good?

But now we want to update Skill #1 a bit to make it more complicated:

Skill #1: Frost 1, CoA: 50%, HA: 100%, EoH: (1) slow enemy down by 40% for 4s and (2) yield 200 damage points. (Please pay attention to the 40% here!)

Or even coming up with more complicated skills:

Skill #3: Frost 3, CoA: 20%, HA: 100%, EoH: (1) frozen enemy for the first 4s then slow enemy down by 50% for next 4s and (2) yield 200 more damage points.

Skill #4: Frost 4, CoA: 10%, attack enemy 3 times continuously, each time: HA: 50%, EoH: (1) frozen enemy for the first 2s then slow enemy down by 50% for next 2s and (2) yield 400 more damage points.

Each effect now has more parameters to be specified — which makes my current schema not fit anymore. Please help deal with this!

what is considered “similar suitably sturdy materials” for Galder’s Tower

Galder’s Tower states

You conjure a two-story tower made of stone, wood, or similar suitably sturdy materials.

What would qualify as "similar suitably sturdy materials"? The relevant definition of sturdy is "strong enough to withstand rough work or treatment." Assuming "similarly" sturdy, could the material be extremely hot stone? Would Mythril or diamond qualify under this?

Galders Tower uses?

Can Galders Tower be summoned on an enemy? Are there any restrictions in the casting/location of the summoning? If you were to keep an enemy monologing or otherwise engaged for 10 minutes, and

Looking for an old adventure module – Heroes explore a tower and find a trapped wizard

I’m looking for an old adventure module and I can’t remember the name.

This is what I remember:

  • For AD&D 1e, and may have been a DM’s Guild publication

  • For low level characters, not more than 5th

  • Wizard is trapped in a magic circle and begs for help

  • One room is a "refrigerator" with a bound ice-elemental to keep it cold

  • One room has a pet basilisk, and anti-stoning spectacles hanging outside the door

  • Magical "elevator" that goes to every floor of the tower, and one floor is "secret"

  • I think the cover art was a B&W drawing of a lone medieval type tower, with lightning bolts flashing around it. The perspective has the viewer looking up at the tower from the ground level.

Is there more information on the spell Galder’s Tower available from previous editions?

I’m playing 5e, and planning my 3rd level spell acquisitions. I came across the spell Galder’s Tower. The spell description says:

You conjure a two-story tower made of stone, wood, or similar suitably sturdy materials.

It then goes on to describe a few more of the tower’s details such as how rooms are furnished and what happens when you upcast the spell. I’m wondering if this is a ‘new to 5e’ spell, and if it isn’t

How can I effectively shield block with a tower shield?

I am a champion with a shield ally and a tower shield. Shield ally adds +2 to my shield’s hardness and 50% HP and BT. So a normal tower shield in my hands has a hardness of 7 and 30 HP.

I want to be able to do two things: use shield block to reduce damage for myself and allies, and use raise shield/take cover to provide AC and cover bonuses.

How can I keep shield block effective past my initial levels? There are some magic shields that increase HP and hardness, but I haven’t seen one that is a tower shield. Are there any shields, class features, feats, or strategies that I can use to keep shield block with a tower shield effective?

How does an IMSI catcher “impersonate” a base station/cell tower?

On reading about IMSI catchers, I keep seeing that they “impersonate” a real cell tower or “base station” so that the phone drops its signal-carried data on that machine while on its way to the intended destination.

What I don’t understand is, how exactly does the IMSI catcher do that, or by what mechanism? What is it doing to trick the phone/SIM/connection into saying “This is a valid stop to drop off data”?

Do tower shields provide cover from all directions?

A Tower Shield allows you to use the Take Cover action, in order to gain Greater Cover from the shield. This is confusing because the cover rules require that a source of cover must be between you and the threat, while shields have no rule that specifies which direction they’re facing.

Usually, the GM can quickly decide whether your target has cover. If you’re uncertain or need to be more precise, draw a line from the center of your space to the center of the target’s space. If that line passes through any terrain or object that would block the effect, the target has standard cover (or greater cover if the obstruction is extreme or the target has Taken Cover). If the line passes through a creature instead, the target has lesser cover. When measuring cover against an area effect, draw the line from the effect’s point of origin to the center of the creature’s space.

Because there’s no rule that tracks the direction of shields, does that imply that a tower shield wielder gains omnidirectional cover from Taking Cover behind their shield?

Can allies take cover behind my tower shield?

I am a champion who is wielding a tower shield. I raise my shield, and then Take Cover. On their turns, can my allies attempt to take cover behind my tower shield also?

The Take Cover action requires:

You are benefiting from cover, are near a feature that allows you to take cover, or are prone.

It isn’t clear to me if an ally standing behind my tower shield is benefiting from cover, or if my shield is a “feature that allows you to take cover”.
