The closest unconditional protection is Mist Body, an equip card that prevents the equipped monster being destroyed by battle. Damage calculation is still performed normally though, so its controlling player will still take damage to their life points as normal.
During Damage Calculation is the optimum time to activate Honest. By asking 'damage calculation', they want to make it clear that the battle phase has progressed to that stage, rather than still being in the step before it, in which multiple chains can be activated and Honest's boost may not be used to full effect.
Answer: The "damage calculation is calculated normally" text in Spirit Reaper(SR) means if your SR is attacked while it's on attack position then you will lose LP for that battle but SR won't be destroyed and sent to the graveyard as a result of battle because of it's card effect.Answer!"Damage calculation" is the damage a player receives either due to a monster attacking or by a card effect. Damage calculation is done during the Damage Step of the Battle Phase. If a card's effect reads something like, When this Defense Position card is attacked and the ATK of the attacking monster is lower than the DEF of this card, after Damage Calculation destroy the attacking monster., then that means after damage is inflicted upon a player the rest of its effect activates destroying the attacking monster. More examples-Reflect Bounder: When card is face-up Attack Position and is attacked by a monster on your opponent's side of the field, before damage calculation is resolved in the Damage Step, this card inflicts damage to your opponent's Life Points equal to the ATK of the attacking monster.This means before damage would be inflicted upon either player by the attack during the Damage Step, the monster's effect activates inflicting damage. Then damage is calculated.The Hunter With 7 Weapons: When this card is Normal Summoned, declare 1 Type of monster. When battling that Type of monster, increase the ATK of this card by 1000 points during Damage Calculation. What this translates into is that during the Damage Step, simple increase this card's attack by 1000.
The monster's ATK only matters during Damage Calculation itself. If a 'weaker' monster attacks a stronger one, but that weaker monster has an effect that boosts its ATK during Damage Calculation, then the weaker monster will survive if it then had the higher ATK. It doesn't matter that afterwards, its ATK goes back to normal - Damage Calculation is the part of the Damage Step where monsters are considered destroyed by battle, and the weaker monster had a higher ATK for that.
Mist Body is an Equip Spell Card. The monster isn't destroyed by battle, but Damage Calculation is applied normally.
It can't be used 'before' damage calculation because its activation condition is 'when you take battle damage from an opponent's direct attack'. You have to wait until after Damage Calculation, after you take the damage.
The Damage Step is still entered, and Damage Calculation still happens.The first part will prevent you, the player, from taking any damage due to the Fortress Warrior being attacked by a stronger monster.The second part prevent the Fortress Warrior itself from being destroyed by that one Damage Calculation.
It is during Damage Calculation that Zenmaines uses its protective effect. All that changes is that Zenmaines would not be destroyed by battle, its controlling player will take damage as normal.
The Damage Step still proceeds as normal, including Damage Calculation. Full-Force Strike simply reduces Battle Damage to players to zero, and the attacking monster can't be destroyed by battle.Full-Force Strike's intended use is to allow a weaker monster to safely destroy a stronger one without being destroyed itself. The time when the defending monster is destroyed is the part of the battle step 'after damage calculation'.
When two monsters battle, both monsters must remain on the field, for Damage Calculation to occur. If a monster leaves the field before Damage Calculation, then that particular battle step ends.If Zubaba Knight attacks a face-up defense positon monster, that monster is destroyed at the beginning of the Damage Step. The battle step ends there, no damage calculation occurs, no damage is dealt to either player, and Zubaba Knight may not declare another attack (unless if a card effect permits).
You enter the Damage Step and Damage Calculation as normal. You compare the ATKs of the two monsters, which will determine if one or both are destroyed by battle, and if the controlling players take any battle damage too.
All Shien's Squire does is prevent the Six Samurai monster from being destroyed by battle, it does not stop Damage Calculation from occurring. If a Six Samurai attacks a monster and the opponent boosts it, Shien's Squire can be used to protect the Six Samurai. Damage Calculation will still go ahead and the attacking player will take battle damage. If the Six Samurai attacked a Set monster, then as per regular game rules the Six Samurai won't be destroyed by battle no matter how high the defender's DEF is. You can still use Shien's Squire but the effect would be wasted, and the attacking player will still take damage.
When monsters attack during the Battle Phase, there are actually multiple "steps" that take place. When a player declares an attack, you enter the "Battle Step". If no card effects are activated that would stop the attack, you enter the "Damage Step" in which face-down monsters are flipped face-up and you actually calculate how much damage is done. It's at this point that a card that reads "during damage calculation only" can be activated or takes effect. For more information on how card effects can work and activate during the Battle Phase, refer to the Related Links section below.

If you look at the structure of the Damage Step, you see that destroyed by battle monsters only go to the graveyard at the end - things like Flip Effects activate and resolve while they are still on the field. So you will conduct Damage Calculation, and Gemini Soldier will be considered destroyed. It is still on the field though, and its effect triggers immediately after Damage Calculation. It is only after this, at the end of the damage step, does it go to the graveyard.
Forbidden Chalice will negate Marshamallon's 'cannot be destroyed by battle' effect. Because Forbidden Chalice changes the ATK of a monster, it can be used in the Damage Step, after Marshmallon is flipped by an attack. If you did this, you will not take the 1000 damage from Marshmallon either - his damage dealing effect activates after Damage Calculation, but will be negated.
